Energy flow is the flow of energy through living things within an ecosystem. All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain. Each of the levels within the food chain is a trophic level.
In the desert, the energy from the sun goes to the plants for photosynthesis. These plants such as: small grass and flowers, shrubs, and cacti, are fed on by herbivores such as the desert squirrel. The energy from the sun is absorbed by the plants and when eaten by the herbivores, they recieve that energy.
