Biological environment. Aquatic plants, algae, aquatic plants, etc.
Fish, small fish, large fish or herbivorous fish, omnivorous and carnivorous fish, etc.
Shrimp, molluscs, snails, mussels, etc.
Water birds, ducks.
Water ancient insects. Frog.
In this way, these living and non-living things interact with each other and depend on each other to form an inseparable whole, and we can think of them as an ecosystem.
A forest, a land, a lake, an ocean, etc., can all be seen as an ecosystem.
-
The eco-bottle mimics an ecosystem in which non-living things provide matter and energy to living things.

Here are a few things I learned:
1. The organisms placed in the ecological tank must have strong vitality, and the number of organisms placed must be appropriate.
2. In order to keep the sand in the ecological tank dry, a plastic sheet can be laid under the sand to prevent the water (gas) in the tank from penetrating up.
3. The stability of the ecosystem is closely related to its species composition, trophic structure and abiotic factors, the stronger the vitality of the organisms originally put in, the more appropriate the number of organisms, the more suitable the environmental conditions, and the longer the maintenance time of the whole ecosystem.
4. Put the made ecological bottle in the sun. Pay attention to the light should not be too strong, so as not to cause the temperature inside the bottle to be too high and affect the survival of organisms.

The components of these ecosystems include:
1. Non-living matter and energy: matter - water, mud in the pond (or sand is fine) 2, producers: get some aquatic plants, there are generally places to buy fish 3, consumers: stocking one or two small fish or snails and the like.
4. Decomposer: There is pond mud, water, and air, and there is no need to deliberately make control experiments, two groups, one is the control group, and all the above components are complete; One is the experimental group, don't put the producers. The role of producers in the ecosystem can be seen through comparisons.

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

1. After making an ecological bottle, first think about what kind of creatures can live in such a limited space? Or first according to what kind of creatures you want to raise, determine what materials to use and how big the ecological bottle is?
2. What kind of creatures do you want to raise, and understand the survival needs of each creature? It is better to analyze the needs of the animals and then the needs of the plants.
3. Consider how much of the creature is put in, and how can the types be coordinated and matched to maintain balance?
4. Consider the order of putting in the substances, first put in non-living things: mud, sand, stone, water, etc.; Then put in the creatures: put the plants first, and wait for the plants to live and put the animals.
5. Consider whether organisms need sunlight?
6. Always pay attention to the biological changes in the ecological bottle, and adjust the balance of organisms and the balance of non-organisms at any time.

The ecological bottle is very simple and very suitable for raising fish at home.

Eco-bottles can simulate a pond ecosystem. It allows us to understand the interactions and influences of various ecological factors in the ecosystem, and deepen our understanding of the natural world.
1 Materials and utensils Aquatic plants (such as algae), aquatic small animals (such as vertebral snails, ring snails), water, sand, glass bottles (such as specimen bottles, large test tubes or medical glucose injection bottles), petroleum jelly.
2 Method steps Bottle handling: Wash the specimen bottle, and scald the bottle and cap with boiling water. Put sand and fill water:
Put 1cm thick sand in the bottle and add water to 4 5 of the bottle volume. Put organisms: After the water in the bottle is clear, put in aquatic plants and aquatic animals.
Cap sealing: Cap the bottle and coat the cap around the cap. Paste the label:
Label the bottle, indicate the date of production and the name of the maker Place the bottle: Place the small ecological bottle on the sunny window sill (do not move its position at will in the future).

Microbial decomposition doesn't matter, it does it automatically;
An enzyme is a biological catalyst produced by living cells in an organism. Most are made up of proteins (a few are RNA). It can catalyze various biochemical reactions with high efficiency and promote the metabolism of organisms under very mild conditions in the body. >>>More

Answer: (1) Improve soil fertility. This is the main effect of biofertilizers, such as various autogenous, combined or symbiotic nitrogen-fixing biofertilizers, which can fix nitrogen in the air and increase nitrogen content in the soil; A variety of microorganisms that decompose phosphorus and potassium minerals, such as silicate bacteria, can decompose potassium feldspar, mica and phosphate rock in the soil, so that the insoluble phosphorus and potassium in them are effective. >>>More
Increase soil organic matter content。Regular application of organic fertilizer can significantly increase the content of soil organic matter, which is conducive to maintaining the stability of soil organic matter and improving the physical and chemical properties of soil. >>>More
