Question

Distinguish Between Grazing food chain and detritus food chain

Answer 1

the main difference between both these types of the food chain is that grazing food chain starts from the green plants, which are the primary producers, whereas detritus food chain begins from the dead organic matter or decomposed material, which is usually present in the soil.  

In the food chain, energy comes from organic matter (or detritus) generated in trophic levels of the grazing food chain. It begins with producers, present at the first trophic level. The plant biomass is then eaten by herbivores, which in turn are consumed by a variety of carnivores.

Answer 2

Differences among grazing type and detritus kind of food chain are :

1. The grazing type of chain of food begins with plants that are green, that is, plants that are capable of making food. Whereas the detritus kind of chain of food begins with dead or decomposed matter.

2. In the grazing type, the energy source is the sun but in detritus type, the source of energy is the decomposed matter or substances.
