The aquatic plants in the ecological bottle carry out photosynthesis, what substances can be eaten a

The fish in bottle A live the longest, because it simulates the cycle of producers and consumers, aquatic plants can carry out photosynthesis, purify the air, and can produce organic matter to feed the fish, and fish feces can provide enough inorganic matter and other trace elements to aquatic plants, so that this bottle can carry out an effective cycle.

Although he can photosynthesize, provide oxygen and food, the nutrients in the water will be depleted soon, which will affect the ability of the aquatic plants to photosynthesize, and eventually the aquatic plants will die due to the lack of trace elements.

The fish in the bottle will die first, and because it is unable to produce oxygen and organic matter on its own, it will suffocate due to lack of oxygen, or starve to death due to lack of food. Hope.

Influential! Aquatic plants or algae provide oxygen, food, living environment (e.g., shelter, etc.) and purify water to absorb excessive nutrients.

The eco-bottle is a sealed ecosystem, just like the earth. The eco-bottle consists of a transparent glass sphere containing small shrimp, algae, bacteria, and a filtered marine eco-bottle.

Water, gorgonia, boulders, and air (gorgonia is an inanimate dendritic substance).The small stones in the eco-bottle represent the earth's land, with about two-thirds of water and one-third of air, and the energy** is also sunlight, and of course, life: shrimp, algae and bacteria.

The ecological cycle carried out in the eco-bottle represents a simplified ecological cycle of the earth. Light and carbon dioxide in the water allow algae to photosynthesize and produce oxygen, and they use the inorganic nutrients in the water, so the algae are the producers in the system. Shrimp are consumers because they use oxygen to breathe, release carbon dioxide, and feed on algae and bacteria to excrete waste. Bacteria decompose the excrement of small shrimp into inorganic nutrients for algae, so bacteria become decomposers. Gorgonia and boulders provide a hiding place for microorganisms to avoid being eaten by shrimp, and a place for bacteria to grow and act as decomposers to break down waste in the ecosystem.

Therefore, the food and gas in the eco-bottle can be continuously recycled. The eco-bottle is airtight, so no food or gas can be added, and the only thing that can enter the system is light, which is also powered by light.

Photosynthesis usually refers to the process by which green plants absorb light energy, synthesize carbon dioxide (CO2) and water (H2O) into energetic organic matter, and release oxygen at the same time. So, what is the process of photosynthesis? Here is some relevant information for your reference!

A brief description of the process of photosynthesis What is the basic process.

1 What is photosynthesis.

Photosynthesis means the synthesis of light, and it is also the chloroplast of plants, green plants, animals and some bacteria, under the irradiation of sunlight, will go through the reaction of light and carbon, and use photosynthetic pigments to convert carbon dioxide, hydrogen sulfide and water into organic matter, and release a process of yang energy, and it can also be said to be the conversion process of chemical energy energy in organic matter with light energy.

Photosynthesis refers to the process in which green plants use light energy to convert carbon dioxide and water into organic matter that stores energy and release oxygen. We are inhaling the oxygen released by photosynthesis all the time. The food we eat every day also comes directly or indirectly from organic matter produced by photosynthesis.

2. Photosynthesis reaction process.

Light reaction stage: The chemical reaction in the first stage of photosynthesis must have light energy to proceed, and this stage is called the light reaction stage. The chemical reaction in the photoreaction stage is carried out on the thylakoids within the chloroplast.

Dark Reaction Stage: The chemical reaction in the second stage of photosynthesis, which can be carried out without light energy, is called the dark reaction stage. The chemical reactions in the dark reaction phase are carried out in the matrix within the chloroplast.

The light reaction stage and the dark reaction stage are a whole, and in the process of photosynthesis, the two are closely related and indispensable.

The importance of photosynthesis: Photosynthesis provides the material and energy for the survival of almost all living things, including humans. Therefore, photosynthesis is of great significance for humans and the entire biological world.

3. What is the significance of photosynthesis.

1. Transform inorganic matter into organic matter. About 51 011 tonnes of organic matter are synthesized annually and can be used directly or indirectly as food for humans or the animal kingdom, and it is estimated that the autotrophic plants on Earth assimilate about 21 011 tonnes of carbon a year through photosynthesis, of which 40 are assimilated by phytoplankton and the remaining 60 by terrestrial plants;

2. Convert light energy into chemical energy, green plants convert sunlight into chemical energy in the process of assimilating carbon dioxide, and accumulate it in the formed organic compounds. The energy used by human beings, such as coal, natural gas, wood, etc., is formed by plants in the present or past through photosynthesis;

3. Maintain the relative balance of atmospheric O2 and CO2. On Earth, about tons of O2 are consumed per year due to biological respiration and combustion, and at this rate, the O2 contained in the atmosphere will be depleted around 3000 years. However, green plants absorb CO2 and release tons of O2 per year, so the O2 content in the atmosphere remains at 21.

The eco-bottle is an interesting, energetic and very useful tool in science teaching activities, which is "a small number of plants, animals and other non-living substances that feed on these plants into a closed light-mouthed bottle to form an artificial simulation micro-ecosystem". Because most children like to raise and watch fish and other various aquatic creatures in ecological bottles, this kind of breeding and viewing can increase knowledge, promote **, enhance understanding, and bring beauty enjoyment.

Scientific principles. Hansheng, a scientist at NASA's Advanced Life Support Program at NASA's Rocket Propulsion Laboratory, has discovered that tiny saltwater shrimp, algae and snails can survive in a closed system for a long time. Aquatic weeds grow algae under photosynthesis; Small shrimp eat algae to survive; Nitrifying bacteria break down the excrement of shrimp into nutrients for aquatic plants.

These three organisms form a symbiotic and self-contained "miniature world" within this closed system.

The eco-bottle is a sealed ecosystem, just like the earth.

The eco-bottle consists of a transparent glass sphere containing shrimp, algae, bacteria, filtered seawater, gorgonia, boulders, and air (gorgonia are inanimate dendrites.

Summary. Aquatic plants absorb light energy during photosynthesis, converting carbon dioxide and water into organic matter and oxygen. This process can be judged by observing the growth and color of aquatic plants.

If the aquatic weed is growing well, has plump leaves, and is bright green in color, then it is likely to be photosynthesizing.

Aquatic plants absorb light energy during photosynthesis, converting carbon dioxide and water into organic matter and oxygen. This process can be judged by observing the growth and color of aquatic plants. If the aquatic weed grows well, the leaves are full and respectful, and the color is bright green, then it is likely to be photosynthesizing.

I'm still a little confused, can you be more detailed?

During photosynthesis, aquatic plants absorb round light energy and convert carbon dioxide and water into organic matter and oxygen. This process can be judged by observing the growth and color of aquatic plants. If the aquaweed is growing well, has plump leaves, and is bright green in color, then it is likely to be photosynthesizing.

In addition, if oxygen bubbles are observed near aquatic plants, it is also a clear sign of photosynthesis. In addition, if a photosynthesis measuring instrument is used near aquatic plants, the oxygen released by aquatic plants during photosynthesis can be measured. This is also a way to tell if aquatic plants are photosynthesizing.

Light is the most important factor in photosynthesis in all plants. Without light, aquatic plants cannot photosynthesize, absorb carbon dioxide and produce oxygen. will not be able to sustain its own survival.

Light is important and needed for aquatic plants. However, there is also a certain limit, if the light is too strong or the light time is too long, the branches and leaves of aquatic plants will grow green moss, which will affect the photosynthesis of aquatic plants; However, if the light is too weak or the light time is too short, the branches and leaves of aquatic plants will turn yellow or even die due to too little photosynthesis.

So how can we make aquatic plants receive light more reasonably? If you set up a fish tank in a sunny room, it is best to receive about an hour of sunlight in the morning and evening when the sun is not enough, and never accept direct sunlight. If you set up a fish tank in a room without sunlight, you should use a light to irradiate the aquatic plants, and the time when the light shines on the aquatic plants is generally 60 watts of incandescent bulbs or 40 watts of fluorescent lamps for about six hours a day.

Morning, noon, and evening in nature. Sunny days and rainy weather will change the wavelength of light waves. Aquatic plants can all grow normally. A specific wavelength of light waves has a significant effect on photosynthesis, but different plants have different requirements for this specific wavelength.

Artificial ornamental planting should take into account the ornamental effect, and the photosynthesis intensity of aquatic plants is not the main focus.

There is also the right temperature and light.

It's certainly credible, your friend is right, but you don't need to take it out, because the fish will float to the surface to breathe on their own, and it's best to keep the tank in a sunny place. This is photosynthesis.

Oh, yes. Undergoes photosynthesis during the day, releasing oxygen. There is no light at night, so you can't photosynthesize, but plants also have to breathe and compete with fish for oxygen, so your friend is right

Photosynthesis is a biochemical process in which green plants and algae use photosynthetic pigments such as chlorophyll and certain bacteria (such as halophilic archaea with purple membranes) use their cells to convert carbon dioxide and water (hydrogen sulfide and water for bacteria) into organic matter and release oxygen (hydrogen for bacteria) under the irradiation of visible light. Plants are called producers of the food chain because of their ability to produce organic matter from inorganic matter and store energy through photosynthesis. Through consumption, consumers in the food chain can absorb the energy stored by plants and bacteria with an efficiency of about 10% to 20%.

For almost all living beings in the biological world, this process is the key to their survival. And for the carbon and oxygen cycle on Earth, photosynthesis is indispensable.

Photosynthesis can be divided into two stages: light reaction and carbon reaction (formerly known as dark reaction).

Photoreactions: Conditions: light, photosynthetic pigments, photoreactive enzymes.

Location: thylakoid membranes of chloroplasts. (pigments).

Reaction to photosynthesis:

raw material) light (product).

Water + carbon dioxide --- organic matter (mainly starch) + oxygen (light and chloroplasts are the conditions).

Carbon reaction: The essence of a carbon reaction is a series of enzymatic reactions. Originally called dark reaction, as research deepened, scientists found that this concept was not accurate. This is because the so-called dark reaction can only be carried out for a very short time in the dark, but it can be carried out continuously and regulated by light under the condition of light.

So at a photosynthesis conference in the 90s of the 20th century, scientists engaged in plant physiology unanimously agreed to change the name of the dark reaction to the carbon reaction.

Conditions: Carbon Reactive Enzymes.

Location: Chloroplast matrix.

Influencing factors: temperature, CO2 concentration, pH, etc.

There is light, water, and carbon dioxide in the water, and there are photosynthetic pigments, photoreactive enzymes, and carbon reactive enzymes on the green leaves of the grass, so photosynthesis can be carried out.

There can be light, water, and carbon dioxide in the water, and there are photosynthetic pigments, photoreactive enzymes, and carbon reactive enzymes on the green leaves of the grass, so photosynthesis can be carried out.

1. Water is a liquid, and a solution is a liquid containing other solutes.

2. There is an experiment in the biology book: in a closed environment, plants can survive in a closed environment with only soil, water, and air, so if the solution you mentioned contains certain nutrients, then it can theoretically survive in a place with light.

3. Although green plants can release oxygen through photosynthesis at a certain concentration of carbon dioxide and under light, and carbon dioxide can also be released through respiration, pay attention to the premise of light. So it can't just be carbon dioxide.
