Question

What are the types of food chains in an ecosystem? grazing, detritus, both A and B, none of these. ​

Answer 1

Mostly food chain of grazing food chain but some other detritus also as in the case of terrestrial food chain

Answer 2

Answer==>>

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.

This type of chain thus depends on autotrophic energy capture and the movement of this captured energy to herbivores. Most of the ecosystems in nature follow this type of food chain. The phytoplanktons →zooplanktons →Fish sequence or the grasses →rabbit →Fox sequences are the examples, of grazing food chain.

2. Detritus food chain:

This type of food chain goes from dead organic matter into mi­croorganisms and then to organisms feeding on detritus (detrivores) and their predators. Such ecosystems are thus less dependent on direct solar energy. These depend chiefly on the influx of organic matter produced in another system. For example, such type of food chain operates in the decomposing accumulated litter in a temperate forest
