Answer to Question 1

Energy is captured through photosynthesis or chemosynthesis by autotrophs or primary producers. Primary producers are eaten by heterotrophs called primary consumers, which are in turn eaten by secondary consumers. Consumers which have no predators themselves are called top consumers. There are many small primary producers at the base of the trophic pyramid, and a very few large top consumers at the apex. Only about 10 of the energy from the organisms consumed is stored in the consumers as flesh, so each level is about one tenth the mass of the level directly below it. The rest of the energy is lost as waste heat as organisms live and work to maintain themselves.
