Question

If 20,000 K Cal energy is available at the level of producers, what will be the amount of energy available at the level of secondary consumers.

Answer 1

Give:

Energy at producer level = 20,000 K Cal

Solution:

Using the 10% law of energy transfer, only 10% of energy is passed to the next trophic level.

Primary consumers (herbivores):
= 10% of 20,000

= 2,000 K Cal

Secondary consumers (carnivores that eat herbivores):
= 10% of 2,000

= 200 K Cal

So, the energy available at the level of secondary consumers is 200 K Cal.
