what is the function of decomposers in biochemical cycles?

use of carbon cycle?

organisms and their role in nitrogen cycle?? 

importance of nitrogen cycle?

Hi Gayathri,

Role of Decomposers: Decomposers are organisms that breakdown plant and animal remains into simple nutrients that can be simply absorbed by the soil. Decomposers play an important role in the biogeochemical cycling of nutrients in the environment as they are responsible for the breakdown and return of nutrients back to the environment in their native state.

Importance of Carbon cycle: Carbon cycleis important because all liiving organisms need carbon. All organic substances are made up of carbon. Fats, vitamins, nucleic acids, carbohydrates, and proteins contain carbon as a structural component.

Role of organisms in nitrogen cycle: Certain forms of bacteria are able to convert atmospheric nitrogen into usable forms such as nitrates and nitrites. Such nitrogen fixing bacteria are commonly found in the roots of legumes (plants of pulses) inside special structures called root nodules. These usable forms of nitrogen are absorbed by plants to produce many compounds such as amino acids, which in turn form proteins. When an animal feeds on plants, nitrogen enters its body.
