The circle of life, in which energy flows into the world from the sun, giving plants that energy to live.  All of the organisms in an ecosystem are chemical machines driven by the energy captured in photosynthesis. The organisms that first capture energy, the producers, include plants, some kinds of bacteria, and algae. All other organisms in an ecosystem are consumers.

The plants energy will then be transferred to a small animal, most likely a rabbit or maybe a mouse; depending on the plant. The small animal will then be eaten by a bigger more dominating animal like an eagle or a snake. It just goes on and on. The eagle or the snake will get eaten by a bigger animal or will decompose into the earth giving the soil and plants around it that same energy.
