Why do algae plants provide oxygen to humans?

The photolysis process of water in the photosynthesis photoreaction phase can release oxygen because algae plants have chloroplasts in their bodies and are capable of photosynthesis.

Unlike animals, plants do not have a digestive system, so they must rely on other means for their nutrient intake. It's the so-called autotrophs. For green plants, during the sunny day, they will use the energy of sunlight to photosynthesize to obtain the nutrients necessary for growth and development.

The key players in this process are the chloroplasts inside. Under the action of sunlight, chloroplasts convert carbon dioxide and water absorbed by the roots into glucose and release oxygen by the chloroplasts

12H2O + 6CO2 + Light C6H12O6 (glucose) +6O2 + 6H2O

Oxygen is produced when there is photosynthesis.

Hailing Collapse Ecosystem.

is a huge ecosystem, covering 70% of the Earth's surface. It is divided into coastal ecosystems, surface ocean ecosystems, coral ecosystems and pelagic ecosystems. There are many species of organisms that live in the ocean (more than 250,000 species are known).

from prokaryotes.

to vertebrates. Most animals are able to swim in the water and <>

Since algae and planktonic plants contain the same chlorophyll as land plants.

They can absorb solar energy to synthesize carbon dioxide.

i.e. photosynthesis.

and produce oxygen. Some are dissolved in seawater, some are dispersed in seawater, and those dissolved in seawater will evaporate from the heat of sunlight and release dissolved oxygen into the water, because water represents 3 4 of the earth, algae live in water, so 90% of the oxygen on earth should come from algae algae with simple structure, without differentiation of roots, stems and leaves, chloroplasts in cells.

Photosynthesis and the release of oxygen throughout the body. 90% of nature's oxygen is produced by algae. Therefore, algae are important oxygen in the air**, which contributes to the balance of carbon dioxide in the biosphere.

In addition to large trees, shrubs, herbaceous plants, felts, mosses and lichens.

Photosynthesis is also carried out to produce oxygen. Algae play a greater role. Ground algae produce the greatest percentage of oxygen because the Earth's water area is much larger than the land area, and the algae distribution range is much larger than that of the Earth's vegetation In nature, the number of algae is extremely large and extremely widespread.

Algae plants have a simple structure, roots, stems, leaves, and chloroplasts do not differentiate in cells, and the whole body can carry out photosynthesis and release oxygen. 90% of nature's oxygen is produced by algae plants. Therefore, algae plants are important oxygen in the air**.

Since the solubility of oxygen in water is very small, the ** of oxygen can be guaranteed, so the algae has a good oxygen production effect.

Because the ocean area is relatively large, in this case, there are more algae in the sea, and the blind algae appeared very early, and there are some evolutions, so the oxygen production capacity is relatively auspicious.

Because trees are mainly used to absorb carbon dioxide from the air, they are not as active as algae, so their ability to produce oxygen is not as strong as that of algae.

Because the area of the ocean is relatively large, there are more algae in the sea if you do a balance, and the algae appeared very early, and they also have some evolution, so the oxygen production capacity is relatively good.

Because the solubility of oxygen in water is very small, the condition of oxygen can be guaranteed, so the effect of algae oxygen production is good.

Plants on earth undergo photosynthesis.

carbon dioxide in the air.

Oxygen is reduced to oxygen and the water drawn from the roots of plants is decomposed to release oxygen. Part of ** for cyanobacteria.

Bacteria, this microorganism has completely changed the Earth's atmosphere. They emit oxygen in the form of waste, filling the Earth's atmosphere with oxygen. According to rock evidence, there was a sudden increase in the amount of free oxygen in the atmosphere about 2.6 billion years ago, and it is believed that the rapid increase in oxygen on Earth was caused by photosynthesis by seaweed plants.

Makes up the solar system.

The original nebula is a nebula rich in many elements such as hydrogen and oxygen, which are preserved to form water under suitable conditions and form ice in suitable conditions. The vast majority of oxygen in the air is tritary. Ultraviolet radiation and the energy transfer of some organic molecules to oxygen are the main reasons for the formation of singlet oxygen.

The oxidation capacity of singlet oxygen is higher than that of triplet oxygen. Since the emergence of cyanobacteria on Earth, the amount of oxygen has increased, life has gradually evolved in the direction of repetition and repurity, and over time, plants have begun to appear on land. Photosynthesis in plants became the most common type of oxygen**.

According to research, the algae in the ocean produce more than 90% of the oxygen in the earth's wide open air every year, maintaining the dynamic balance of oxygen on the earth. While the Sirans produce oxygen through photosynthesis, huge amounts of inorganic carbon such as carbon dioxide are converted into organic compounds that provide nutrients for the sea.

Algae blooms in large quantities can lead to DU

Oxygen in the water decreases.

zhi analysis:1Algae blooms in large quantities and consumes a large amount of oxygen in the water body (aerobic respiration, which is used for the growth and reproduction of the algae themselves, etc.).

2.The oxygen in the water mainly comes from underwater plants such as aquatic plants, and algae bloom and cover the water surface, making it impossible for underwater plants to get enough light and severely reducing photosynthesis.

This ultimately leads to a decrease in the amount of dissolved oxygen in the water body.

Algae doesn't just release oxygen, it breathes oxygen. Algae put the water.

The whole coverage of the back surface causes the external oxygen to dissolve in the water, and the fish organisms in the water still have to breathe oxygen, and the oxygen is relatively difficult to dissolve in water, and most of the oxygen produced by the algae enters the air. Therefore, it is not enough for the algae to release oxygen to sustain themselves and the aquatic organisms in respiration. After the algae bloom, the oxygen in the water will decrease, because the algae itself also consumes oxygen (in the case of a large number of algae, the amount of oxygen released by the algae will be less than the amount absorbed), resulting in the collective death of anoxic fish and other organisms in the water, and the water rots and stinks, which is called red tide.

The eutrophication of water quality will lead to the bloom of algae, and in the early stage of algae bloom, DAO will produce junior college.

The amount of oxygen, but the dissolved oxygen of the water genus is very poor, and the life cycle of algae is very short, and when they die naturally, there is oxygen to break down organic matter. This consumes more oxygen, which leads to a lack of oxygen in the water and a large number of fish and shrimp die. This leaves more organic matter to decompose and the oxygen demand is greater......The vicious circle ......

Answer: Most of the algae plants live in the water, a few live on the land, and more than 70% of the earth is the ocean, therefore, the number of algae plants in nature is extremely large, and the distribution is very wide Algae plants have a simple structure, no differentiation of roots, stems and leaves, chloroplasts in the cell, the whole body can carry out photosynthesis, release oxygen and check the difference, 90% of the oxygen in nature is produced by algae plants, so algae plants are important for oxygen in the air

1. It has the effect of purifying the environment and providing oxygen. Algae release oxygen, which can promote the activity of fine cave fungus, which can accelerate the decomposition of organic matter in the water and purify the sewage.

2. Some algae have the ability to absorb and disperse harmful elements, and reduce the harmful elements in the environment. Oxygen is released through photosynthesis for humans to breathe in animals.

1. It has the effect of purifying the environment and providing oxygen in the main hole. Algae release oxygen to disperse gas, which can promote the activity of fine flushing sedan bacteria, so as to accelerate the decomposition of organic matter in the water and purify the sewage.

2. Some algae have the ability to absorb and accumulate harmful elements, reducing harmful elements in the environment. Oxygen is released through photosynthesis for humans to breathe in animals.

Most of the oxygen on the earth is mainly based on algae plants in the ocean**, at the beginning of the birth of the earth, the emergence of oxygen is produced by the photosynthesis of microorganisms in the ocean, and then with the continuous increase of oxygen amount, to a certain proportion, aquatic algae are produced.

So, the answer is algae plants in the ocean.

Algae. The number of this thing is not in the same order of magnitude as other plants.

During the day, plants seem to only photosynthesize, inhale carbon dioxide and exhale oxygen, but at night, when the sunlight is gone, photosynthesis stops, and at this time, plants can only respire, inhale oxygen, and exhale carbon dioxide. Plants need oxygen for respiration just like humans, but because photosynthesis is greater than respiration, plants generally absorb carbon dioxide and release oxygen. Without air, plants will suffocate and starve, and sometimes the roots of drought-tolerant crops such as soybeans and cotton will die because they cannot breathe normally due to the lack of oxygen.
