Producers are autotrophs that can synthesize organic matter from simple inorganic matter. It can convert solar energy into chemical energy through photosynthesis, and convert inorganic matter into organic matter not only for its own development and growth, but also for other organisms to provide material and energy, which occupies the most important position in the ecosystem.
In freshwater ecosystems, phytoplankton are mainly phytoplankton-algae, as well as some rooting plants or floating plants that grow in shallow water (plants in freshwater ecosystems are divided into: floating plants, upright plants, and diving plants). Producers in forest and grassland ecosystems are green plants such as herbaceous plants, shrubs, and trees.
In the deep sea and other similar ecosystems, producers are chemical energy synthesizers (sulfur bacteria) that can use reduced inorganics such as hydrogen sulfide.
Producer in an ecosystem refers to inorganic trophic organisms (autotrophs) or groups of organisms from the perspective of trophic dynamics. is to use the word first. Also known as the primary prodncer, it is the basis for the trophic level.
In ordinary ecosystems, green plants (including microorganisms) with photosynthesis ability are the vast majority, and because they are responsible for most of the organic matter production, most of them only call green plants producers. However, in special ecosystems, there are many organisms that carry out chemical synthesis, and there are many organisms with this function in lakes. In addition, from the perspective of energy, the organisms that perform chemical synthesis are not regarded as producers, but as converters.
In a closed, stable ecosystem, producers produce at a greater rate (volume) than consumers or decomposers. The word producer was first used in connection with biological production. At that time, the usage was different from the above, and instead the plant or herbivore was seen as a primary consumer.
But this usage has almost ceased to be used since.

Ecosystem, referred to as eco, is the abbreviation of ecosystem, which refers to a unified whole composed of organisms and the environment in a certain space in nature, in which organisms and the environment influence and restrict each other, and are in a relatively stable state of dynamic equilibrium in a certain period of time. The range of ecosystems can be large or small, intertwined, and the solar system is an ecosystem.
The sun is like an engine that continuously feeds the solar system. The largest ecosystem on Earth is the biosphere; The most complex ecosystems are tropical rainforest ecosystems, where humans mainly live in artificial ecosystems dominated by cities and farmland. Ecosystems are open systems, and in order to maintain their stability, they need to constantly input energy, otherwise they are in danger of collapsing.
Many basic substances are constantly circulating in the ecosystem, among which the carbon cycle is closely related to the global warming effect, and the ecosystem is a major structural and functional unit in the field of ecology, which belongs to the highest level of ecological research. The dynamic mechanism of ecosystems is also of great guiding significance for human economic activities and the restoration and reconstruction of damaged ecosystems.
Ecosystem is a natural whole with self-regulating functions formed by biological communities and abiotic environments through energy flow and material circulation within a certain range of time and space.
The purpose and object of root fibrillary data research and the delineation of the scope of ecosystems. The largest is the biosphere, which includes all living things on Earth and the conditions in which they live. A small forest, a meadow, or a pond can all be regarded as an ecosystem.

Producers play a fundamental role in the biome, they assimilate the energy in the inorganic environment, and the assimilation amount is the total energy input into the ecosystem, maintaining the stability of the entire ecosystem.
Producers in ecosystems are autotrophs or green-type coarse plants that can synthesize organic matter from simple inorganic matter.
It can convert solar energy into chemical energy through photosynthesis, or convert inorganic matter into organic matter through chemical energy synthesis, which not only provides its own development and growth, but also provides material and energy for other organisms, and occupies the most important position in the ecosystem.
Autotrophic organisms are producers in the ecosystem and are the main components of the ecosystem, and it should be noted that in addition to green plants, bacteria that can carry out chemosynthesis (nitrifying bacteria, etc.) are also producers. Stool beating.
Decomposers can decompose various inanimate complex organic matter (corpses, feces, etc.) in the ecosystem into water, carbon dioxide, ammonium salts and other substances that can be reused by producers, completing the material cycle, so decomposers, producers and the inorganic environment can form a simple ecosystem.
Consumers play a role in the ecosystem to speed up the flow of energy and the cycle of matter.

Producers are the source of organic matter and energy in the ecosystem, producers fix external energy into organic matter through photosynthesis or chemoenergy, consumers obtain energy by ingesting producers, and decomposers obtain energy by decomposing organic matter. Without producers, ecosystems would not exist and would no longer exist.
The corpses of the producers cannot be decomposed, resulting in the accumulation of a large number of producer corpses, and the absence of decomposers will make some nutrients unable to return, and the producers will eventually die due to the lack of some necessary nutrients, and the entire ecosystem will collapse.
Yes, all greenery.
No. In natural ecosystems, all consumers live on nutrients made by producers.
There are few producers in urban ecosystems, and the nutrients produced by producers do not meet the needs of consumers. An urban ecosystem is an ecosystem of development, where both material and energy are imported from the outside world.
Plant. Yes, otherwise there would be no source of ecosystem energy (the energy of the ecosystem comes from solar energy, and producers convert solar energy into chemical energy)!
Consumer. The role of decomposers in the ecosystem is extremely important, without them, the corpses of animals and plants will pile up, the matter will not be able to return, and the ecosystem will be destroyed.
How can it be? How does vegetation grow? Don't need to absorb nutrients? Isn't the process of absorbing nutrients a drain? If only production is done without consumption, then the total energy on the earth is not expanding rapidly?
Rice is a producer in the agro-ecosystem. Producers are mainly biologically classified as various green plants, and rice is one of the green plants. Rice itself is autotrophs, and rice plants and photosynthetic bacteria use solar energy for photosynthesis to synthesize organic matter.
Rice and other agricultural crops assimilate energy from the inorganic environment, and the amount of assimilation is the total amount of energy input into the ecosystem, which maintains the stability of the entire ecosystem. In the process of plant growth, maturation and threshing, rice produces organic matter such as rice grains, straws, and rice husks. People eat rice and participate in the loop of the agro-ecosystem as consumers.
It should be urban and farmland ecosystems.
In natural ecosystems, because the previous trophic level has to feed the next trophic level, there is a loss in the process of energy transfer. Therefore, the energy should follow the principle of less and less, and the energy of the previous trophic level must be more than the next trophic level in order to feed the next level of organisms, so there will be no inverted pyramid shape. >>>More
Answer] False. Answer analysis] Question analysis: A complete ecosystem is composed of biological parts and abiotic parts, while the biological part includes producers (green plants), consumers (animals) and decomposers (bacteria, fungi), and the abiotic part refers to factors such as light, temperature and water that affect the survival of living organisms. >>>More
1. From an ecological point of view, it refers to the process by which organisms form their own bodies or leave them to their offspring. Bioproduction refers to the total amount of organisms formed and their excretions over a certain period of time. >>>More
Phytoplankton, that is, planktonic algae, is the main primary producer of freshwater water bodies, and the phytoplankton community responds very quickly to environmental changes, and is a general term for several algae that live suspended in water. Phytoplankton are widely found in rivers, lakes and oceans, and are affected by natural conditions such as water flow, water temperature, nutrients, light, and biological factors such as algae death, sedimentation, aggregation, and predation, and are very sensitive to environmental changes. The abundance and dominant populations of phytoplankton can effectively reflect the impact of human activities on the ecological environment of water bodies. >>>More
