This releases nutrients that can then be re-used for plant and microbial production, and returns carbon dioxide to the atmosphere or water where it can be used for photosynthesis. They eat primary producers and get the energy indirectly in different forms. Thus, the different plants and animal species are linked to one another through food chains. This is the amount of stored chemical energy biomass that the communities synthesize for the ecosystem. With tertiary production referring to carnivorous consumers , but is more commonly defined to include all biomass generation by heterotrophs. The process of photosynthesis, plants capture energy from light and use it to combine carbon dioxide and water to produce carbohydrates and oxygen.
