Question

What proportion of energy is transferred from one trophic level to the next in an ecosystem

Answer 1

10% of energy

Step-by-step explanation:

Within an ecosystem, there occurs a transformation of energy from one trophic to the next. This leads to the transfer of energy from the primary producers to the consumers as well as the decomposers. Looking at the earth's ecological pyramid, out of the total energy, only 10% of the energy is transported to the next trophic level, and the remaining 90% is lost as heat energy. This forms a chain. where the organisms are depending on each other.

Answer 2

10 % energy of one trophic level is carried to the next trophic level.

Step-by-step explanation:

Organisms at each trophic level consume some of their available energy for respiration and maintenance. Therefore, 10% energy from the organisms of one trophic level is available for the organism of the next trophic level. This is also called as 10% law of energy transfer and determines the energy efficiency of food chains in the ecosystem. For example, if grasses in a food chain have 100 calories, only 10 calories are available for a herbivore such as a deer.
