Question : Distinsuish between : (a) Grazzing food chain detritus food

1.	Question : Distinsuish between : (a) Grazzing food chain detritus food chain (b) Production and decomposition.
Answer» Solution :(a) Grazing FOOD chain : in this food chain energy is derived from the sun. It began with producers present at the first trophic level. The plant biomass is then eatenby herbivoes , which in the true are comsumed by a variety of carnivores. * The food chain is usually large. detritus food chain: * In this food chain, energy comes form organic matter ( or detritus ) generated in trophic levels of the grazing food chain . * It beings with detritus such as dead bodies of animals of fallen leaves which are then EATEN by decomposers pr detritivores . These detritivaroes are in turn consumed by the predators. * It is usually smaller as compared to the grazing food chain . (b) Production: * It is the rate of producing organic matter (food) by producers. It depends on the photosynthetic CAPACITY of the producers. Sunlight is required by the plants for primary production. Decompositon: * It is the PROCESS of breaking down of complex organic matter or biomass from the body of dead plants and animals with the help of decomposers into organic raw MATERIAL such as `CH_(2)`,`H_(2)O,` and other nutrietns. * It occurs with the help of decomposers. *Sunlight is not required for decomposition by decomposers.
