An ecosystem is simply a collection of communities of plants, animals, and microbes interacting together and with their physical environments.
<h3>Energy flow in an ecosystem</h3>
Energy enters the ecosystem through a group of living organisms known as the producers. the producers are mainly the green plants that are capable of photosynthesizing.
Photosynthesis converts solar radiation from the sun to chemical energy in green plants. Another group of organisms in the ecosystem, the primary consumers, feed directly on the producers and as such, are able to gain some energy from them.
The secondary consumers obtain their own energy by feeding on primary consumers. Tertiary consumers feed on the secondary consumers for their own energy and the food chain goes on and on.
Only about 10% of the available energy in one trophic level goes to the next trophic level. The rest of the energy is lost as heat to the surroundings. Thus, the producers have the highest energy in the ecosystem while organisms at the top of the food chain have the lowest energy.
