Plants are the basis of nearly all ecosystems on Earth because they carry out the process of photosynthesis. Plants harvest light energy from the sun and store it as potential chemical energy. When plants are eaten or die, their stored energy becomes available to other organisms. And when predators eat those other organisms, the energy flows into them. Each level at which energy is stored in organisms is called a . When an organism eats a plant, the energy and nutrients stored in the consumed organism flows up to the . This movement of energy through food chains is why models represent plants as the of a food chain or food web.
