Answer 2

Hi dear,

★In ecosystem each and every organisms depends on other organisms for food materials and in this process the energy flow takes place from one trophic level to next trophic level.

★ Level of energy decreases when it flows from one to next trophic level.

★Generally there are 4 trophic system present in the ecosystem :

(A) Producers
(B) Primary consumers
(C) Secondary consumers
(D) Top consumers

★ This has also been observed that there exists five trophic levels in ecosystem that is called as complex ecosystem.

★In a food chain energy flow is *unidirectional* that is from producers to consumers.

★ Usually decomposers like bacteria and fungi are not a part of food chain.

★ Shorter is the food chain, greater will be the energy

Example =>
Grass --> Rabbit --> Fox --> Lion
