Question

Describe different types of food chains that exist in an ecosystem.

Answer 1

The transfer of food energy from the producers, through a series of organisms (herbivores to carnivores to decomposers) with repeated eating and being eaten, is known as food chain.

In nature, basically two types of food chains are recognized – grazing food chain and detritus food chain.

1. Grazing food chain:

This type of food chain starts from the living green plants goes to grazing herbivores, and on to carnivores. Ecosystems with such type of food chain are directly dependent on an influx of solar radiation.

Answer 2

Answer:

There are two types of food chain that exist in the ecosystem 1 Grazing food chain 2 Detritus food chain

Explanation

Grazing food chain It deals with transfer of food energy from green plants to grazing herbivores and from herbivores to carnivores .Grazing food chain consist of producers and consumers.The green plants are producers because they produce energy in form of glucose from sunlight.Herbivores(that consume green plants),carnivores(that consume herbivores) also called secondary consumers belongs to consumer elements.

Detritus food chain In detritus food chain energy is obtained from the consumption of dead material of plant and animal body.Decomposers belongs to this food chain.
