Question

the number of trophic levels in a food chain is limited ,why give an example​

Answer 1

Answer:

The decrease in energy with the higher trophic level limits the number of trophic levels in the food chain or food energy pyramid.

For example: A rat eats grains, a snake eats a rat, which in turn is eaten by an eagle. In a food chain, the number of Tropic levels are limited to 4-5. This is because according to 10% law of energy transfer,only 10%of energy passes from one Tropic level to next.

Answer 2

Answer:

because of the 10% rule by Lindeman

Explanation:

for example if u start with sun to plants then energy received is = 10,000/10 which is 1000kcal

plants to deer= 1000/10 which is 100kcal

deer to lion= 100/10 which is 10kcal

and so on.....

so u see as we go more and more , the energy received gets lesser and lesser.

and so we have a limited number of tropic level
