Give an account of energy flow in an ecosystem.

Explanation

Energy flow in an ecosystem. The study of transfer of energy in different trophic levels is known as Bioenergies
The flow of energy can be studied as:-
(i) energy flow is unidirectional i.e, from producers to secondary consumers and not back
(ii) With each and every trophic level , energy goes on decreasing i.e., energy of the producers `gt` primary consumers `gt` secondary consumers `gt` tertiary consumers . According to Lindemann: Only 10% of total energy received by one trophic level is transferred to next trophic level
Only 1-4% of total solar energy is utilised by plants for photosynthesis , Rest is reflected back, absorbed by water, atmosphere and ground.
