The nitrogen cycle

carnivores fed on herbivores that in turn ,feed on plants.when animals defecate,this waste meterial is broken down b worms and insects,mostly beetles and ants.These small'soil animals'break the waste meterial in to smller bits on which microscopic bacteria and fungi which microscopic bacteria and fungi can act.This meterial is thus broken down further in to nutrients that plants can absorb and use for their growth .In this manner,nutrients are recycled back from animals to plants.similarly,the bodies of dead animals are also broken down in to nutrients that are used by the plabts fir their growth.Thus,the nitrogen cycle on which life is dependent is completed.
The nitrogen fixing bacteria and fungi in the soil give this important element to plants,which absorb it as nitrates.These nitrates are a part of the plant's metabolism,which help in forming new plant proties.This is used by the animals that feed on the plant .The notrogen is then transferred to be the carnivores when they feed on the harbivores.so ,our own lives are closely interlinked to soil animals fungi and even the bacteria in the soil .when we think of food webs,we useually think of the large mammals and other large forms of life.But we need to understand that it is the unseen small animals , plants and microscopic forms of life that are of great value for th efunctioning of the ecosystem .
