Question

short note on ecosystem
​

Answer 1

Answer:

The ecosystem is a community of organisms and their physical environment interacting with each other as an ecological unit, involving the flow of energy. An ecosystem consists of biotic components including living organisms and abiotic components, the physical factors like temperature, rainfall, wind, soil and minerals. An ecosystem can be natural or artificial. Organisms in the ecosystem can be categorised into producers, consumers and decomposers. Food chains describe the feeding relationship between the organisms of an ecosystem. *Producers are the organisms that produce their own food without the help of any other organism. *Consumers are the organisms which cannot produce food but depend on producers for the same. *Decomposers are the organisms which feed on dead and decaying matter. There occurs energy flow in an ecosystem depending on the 10 percent law of energy. Nutrients move through different components of the ecosystem through biogeochemical cycles.
