a) Primary source of energy is dead organic matter called 'detritus' which are fallen leaves, plant parts or dead animal bodies. b) Primary consumers are 'detritivores' including protozoans, bacteria, fungi, etc which feed upon the detritus saprophytically. c) Detritivores are inturn eaten by secon..

Characteristics of a Food Chain - In a food chain, a) there is repeated eating in which each group eats the smaller one and is eaten by the larger one. Thus, it involves a nutritive interaction between the biotic components of an ecosystem. b) the p..
