How the biological balance of the pond is, the organisms living in the pond do not affect each other

The pond should have a producer, a consumer, a decomposer and a good inferiority.

Environment (e.g. water source, soil conditions, etc.). Then, the biome.

The number and type of populations can remain relatively stable for a long time without considering intervention, and the pond is in a state of dynamic ecological equilibrium. If you want to build an ecosystem artificially.

and to maintain a balance, especially to pay attention to the proportion of species and quantity among producers, consumers, and decomposers. The producer should be the main quantity, followed by the decomposer should also be fully considered, and finally the consumer's stocking amount, if the proportion is not well controlled, the Wuji environment will deteriorate.

Objective conditions: sunlight, air, water, soil.

Producers and decomposers are the two "bridges" that connect the biome and the inorganic environment. In ecosystems, producers are able to produce organic matter that provides food and habitat for consumers; Consumers play an important role in pollination, fertilization, seed dispersal, etc. Decomposers are able to decompose the remains of plants and animals into inorganic matter. Without decomposers, the remains of plants and animals would pile up and ecosystems would collapse.

It can be seen that producers, consumers and decomposers are closely linked and indispensable.

There are producers, consumers, decomposers.

A pond is a small pool of water that is oval or rectangular or square and smaller than a river. The ponds are scattered around the village and are called because of the small size of the pond and the water is not deep.

There are ponds in both the south and the north. Ponds can be used to raise hungry fish, lotus roots, and so on. The ponds where fish are raised are larger and the water in the ponds is deeper.

Ponds where lotus roots are planted can be large or small, deep or shallow. Because the lotus root can live as long as there is water and mud. In summer, lotus flowers bloom all over the pond, and the lotus flowers fill the pond with fragrant limbs.

Zhu Ziqing's "Moonlight on the Lotus Pond" vividly depicts the lotus pond in summer.

In the southern ponds, in addition to raising fish and planting lotus roots, they can also be used to wash clothes and vegetables.

However, in the northern ponds, either lotus roots are cultivated or fish are raised, and few people wash clothes and vegetables in the ponds. This difference may be due to the fact that the water in the ponds in the south is clean, so people in the south use it to wash clothes and vegetables. Or because of the difference in life between the North and the South.

The small pond is not small, and it is also a bright spot in the village.

The statement that the organisms that live in the pond do not affect each other is false, the various organisms in the pond live together and they are interdependent and influence each other. For example, in a pond, there will be aquatic plants, fish, shrimp, daphnia, various bacteria and other organisms, as well as non-living things such as water, air, sunlight, temperature, soil, etc., which together form an interactive whole called an ecosystem. The various organisms in the pond live together, and they are interdependent and influence each other.

All the organisms that live in the pond make up the "pond community".

Biological community refers to the distribution of various species in a certain space within a certain period of time, including the populations of animals, plants, microorganisms and other species, which together form a living part of the ecosystem. The various populations of organisms that make up a community are not arbitrarily put together, but are regularly combined to form a stable community.

Each character in a biome has a unique role, such as green plants (such as aquatic plants in ponds) that make organic compounds from inorganic matter through photosynthesis, which is the most important function of a biome. Producers in the community (i.e., green plants, such as aquatic plants) absorb inorganic nutrients such as nitrogen, phosphorus, sulfur, calcium, potassium, magnesium, and other elements from soil or water, and use these elements to synthesize certain organic compounds that form protoplasm and maintain cell functions.

Consumers of animals obtain these elements from eating plants or other animals. When decomposers decompose animal and plant waste products and dead remains, nutrients are released and returned to the environment, where they are then absorbed by plants. This is the nutrient cycle, or biological cycle of matter, and it is through this cycle that all the organisms in the pond can survive and coexist for a long time.

A pond is an ecosystem that belongs to the still-water ecosystem within the freshwater ecosystem.

As a hydrostatic ecosystem, ponds are classified according to their trophic relationships, and the biological components of the ecosystem include producers, consumers and decomposers. Among them, the producers mainly include aquatic higher plants and phytoplankton. In general, phytoplankton production is overwhelmingly dominant in the total primary production of the system.

Phytoplankton are characterized by their small but surprising numbers, their high metabolic rate, fast reproduction rate, short population renewal cycle, and most of their energy is used for the reproduction of new individuals, so their productivity is much higher than that of land plants. Primary consumers of freshwater ecosystems are mainly small zooplankton, and their species composition and population distribution often vary with phytoplankton.

Self-regulation of ecosystems.

The strength of the self-regulation ability of the ecosystem is reflected by the combined effect of multiple factors. Ecosystems with diverse compositions, complex energy flow and material cycle pathways have strong self-regulation ability. On the contrary, the self-regulation ability of ecosystems with a single structure and composition is relatively weak.

Tropical rainforest ecosystems are the most stable and complex ecosystems with the most diverse components and ecological pathways, and Arctic tundra ecosystems are fragile because they are only one producer of lichens, and restoration after destruction is very costly.

An ecosystem is a unified whole composed of biological communities and inorganic environments. There are organisms in the pond and there is also an inorganic environment, so a pond is an ecosystem.

A pond ecosystem refers to the sum of all organisms living in the same pond.

Ecosystems are made up of ecological matter, including all.

Aquatic animals, plants and microorganisms. The most important ecological substances that affect the pond ecosystem are aquaculture aquatic animals, feed, and water bodies.

Microbial species.

The pond ecosystem has the function of self-purification, and the proportion of various ecological substances constituting the water ecosystem is relatively stable, and the functions of ecological substances are different, but each has its own responsibilities to jointly complete the normal cycle of the water ecosystem. If the ecological matter put into the pond ecosystem is moderate, the cycle path.

If the trail is smooth, the pond ecosystem can remain functional.

However, the self-cleaning function of the pond ecosystem is limited, and if a certain ecological substance (such as feed or disinfectant) is injected one-sidedly and excessively, it will be raw.

If the circulation pathway is blocked, the stability will be destroyed, and harmful ecological substances will accumulate in the pond. This is called polluted water.

Therefore, the type and quantity of ecological material inputs have a crucial impact on the pond ecosystem.

A pond ecosystem is a type of freshwater ecosystem. Freshwater ecosystems are natural systems in freshwater that consist of biological communities and their environmental interactions. There are two types of water, still water and flowing water.

Ponds belong to the former. The environment in the pond ecosystem is the abiotic parts such as water, air, and silt, and the animals and plants in the pond are both producers and consumers, there is no absolute producer, and there is no absolute consumer, and interdependence constitutes the ecosystem, and the role of decomposers is played by microorganisms. Generally speaking, the producers in the pond are often grasses, the consumers are aquatic animals such as fish, frogs, turtles, shrimps, etc., and the decomposers are microorganisms such as bacteria.
