Question

Calculate the amount of energy that will be available to big fish in the following food chain, if 10,000 J of energy is available to small algae from the sun :
Small algae → Zooplankton → Fish → Big fish

Answer 1

The amount of energy available to big fish will be 0.1 J. Given 10,000 J of energy is available to small algae from the sun. It can be calculated as follows:

Small algae →	Zooplankton →	Fish →	Big fish
10,000 J →	1,000 J →	100 J →	10 J →

The amount of energy available to big fish is 10 J.
