food chain pyramid

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..

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 plants and animals which depend successively on one another form ..

The study of food chains helps in understanding food relationship and interdependence among various organisms in an ecosystem. The mechanism of transfer of food, energy and nutrients through various components of nature can also be studied The effect ..

a) These are directly dependent upon solar radiations as the primary source of energy and the producers (green plants) synthesize their plant biomass by the process of photosynthesis. Producers form the first trophic level. b) Herbivores or primary consumers eat upon the producers and form the seco..
