Energy is conserved in the ecosystem by some of it being transferred to organisms at the higher trophic levels and the rest being lost as heat to the ecosystem.
Green plants fix solar radiation directly from the sun. Some of the energy in green plants is transferred to the organisms that consume them. Only about 10% of the energy fixed by green plants is transferred to primary consumers while the rest is lost as heat to the ecosystem.
The consumers of primary consumers are also only able to obtain about 10% of the energy they extract from green plants while the rest is lost as heat. Thus, the amount of energy available at each trophic level progressively decreases as we move up the trophic level in the food chain.
