Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What percentage of energy is passed on to each trophic level?
A
10%
B
50%
C
90%
D
100%
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Detailed explanation-3: -Lindemann gave the ten percent law in 1942. This law states that only 10 percent of energy in a food chain out of the total energy is transferred from one trophic level to another. The rest of the energy is utilized for other metabolic processes and some are released as heat.
