Question

In a given pyramid T1

trophic level has 10,000 KJ

a) What will be energy level at T2

, T3 & T4

b) Which was the law applied here.​

Answer 1

A) The energy level at T2 will be 10percent of the before level.

T2= 10,000/100 *10 = 1000

T3= 1000/100* 10 = 100

T4= 100/100 *10 = 10

B) 10% Rule

Definition- The 10% Rule means that when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on. A trophic level is the position of an organism in a food chain or energy pyramid
