Flow Of Energy and Energy Loss In The Ecosystem - SS1 Biology Lesson Note

The flow of energy in an ecosystem is essential for sustaining life and driving ecological processes. It supports the growth, reproduction, and survival of organisms, as well as the cycling of nutrients.

As energy is transferred from one trophic level to the next, there is a decrease in available energy. This is due to energy loss in the form of heat during metabolic processes and incomplete digestion. As a result, energy availability decreases as one moves up the food chain, limiting the number of trophic levels that can be sustained in an ecosystem.
