Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How much energy is passed from one trophic level to another?
A
10%
B
1%
C
15%
D
20%
Explanation: 

Detailed explanation-1: -Only about 10% of the energy is transferred from one trophic level to another. The rest is used for life processes of the organism and some is lost as heat. Q. According to Lindeman’s 10% law, only 10% of energy is transferred to next trophic level.

Detailed explanation-2: -Whenever energy is transformed, there is a loss of energy through the release of heat. Similarly, energy is lost as heat when it is transferred between trophic levels like in a food chain/food web. This makes the flow of energy in an ecosystem unidirectional.

Detailed explanation-3: -Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

Detailed explanation-4: -According to the 10% rule, only 10% of energy is transferred from one level to the next level of food chain, and in the remaining 90% some part is used up metabolically for survival and the rest is lost as body heat.
