In an ecosystem, the `10%` of energy available for transfer from one trophic level to the next is in the form of
A
heart energy
B
light energy
C
chemical energy
D
mechanical energy
Text Solution
Verified by Experts
The correct Answer is:
C
The `10%` of energy available for transfer from one trophic level to the next in an ecosystem is in the form of chemical energy. The autotrophs (or producers) capture the energy in sunlight and convert it into chemical energy. This energy is passed onto other trophic levels to support all the activities of the living world.

Food chains and the energy flow within an ecosystem provide an important understanding of contingencies and mutual dependencies of organisms. The given below flow chart depicts the energy flow within some members of a grassland ecosystem. The grass in the below ecosystem transducer 120,000 J of sunlight and fixes it into 12,000 J of energy. It is established that 90% of the energy of one trophic level is not passed to the next trophic level. Further assume that the energy transferred from one trophic level to the next is equally shared among the different organisms at that trophic level. Based on the above information, indicate the amount of energy that an organism C may have received from an organism from the previous trophic level.
