Question

a) Explain 10% Law in reference to the flow of energy across various Trophic Levels.

(b) Find out the amount of Energy available to Eagles in a Food Chain consisting of Carrots -

rabbit - snake – eagle. Assume 1, 000 J of energy is available to Carrot plants from the Sun.

Answer 1

10% law: At every trophic level,energy is lost about90% and energy transferred to next level is only 10%.This is ten percent law.

Energy absorbed by carrots=1000J.
energy absorbed by rabbit is 100J.
energy absorbed by snake is 10J.
and energy absorbed by eagle is 1J.

Answer 2

According to 10%law only 10%of the total energy is passed to next trophic level
eagle is the last trophic level to it recieves very less enegy
it is only 1
