types of food chains

Types of Food Chains - There are mainly two types of food chains operating in nature. a) Grazing food chain b) Detritus food chain. Grazing food chain is generally seen in ecosyst..

Grazing food chain is generally seen in ecosystems such as grassland, pond or lake where a substantial part of the net primary production is grazed on by herbivores (cattle and rodents). Usually upto 50% of the NPP is grazed on by these animals in their respective ecosyste..

. Certain food chains may be very long and may extend to fourth, fifth or even higher order consumers. Food Chains in Aquatic Ecosystems In aquatic ecosystems of the biosphere, like fresh water ponds, lakes or sea, the food chain starts wi..

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 plants and ..

While studying the biotic components in an ecosystem we have realised that food prepared by green plants is consumed by a series of consumers, both herbivores and carnivores, and finally broken down into their elements and released back into nature by decomposers in nature. The nutritiona..

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..
