State the points of explanation which are derived from the study of flow of energy in an ecosystem.

Explanation

From the study of flow of energy in an ecosystem, following points of explanation are derived:
( 1 ) The green plants capture only about 1 % of the energy from the total available solar energy and convert it into food.
( 2 )A large amount of energy is lost as heat to the environment during the flow of energy from one trophic level to next.
( 3 ) Compared to producers, consumers utilise more energy.
( 4 ) Continuous supply of energy is reqUired for an ecosystem
( 5 )At every trophic level, organisms utilise energy for growth, reproduction, etc
( 6 ) On an average, 10 % of available energy gets transferred from one trophic level to next in food chain
( 7 ) Food chains generally consist of three or four steps. After four trophic levels very little usable energy remains in the food chain.
( 8 ) Producers occur in the largest number whereas top level carnivores are in the smallest number.
