The document discusses how energy from the sun is incorporated into biomass through producers, consumers, and decomposers in a food chain or web. It defines producers as organisms like plants that can produce their own food, consumers as organisms that obtain energy by eating other organisms, decomposers as organisms that break down waste and dead materials, and provides examples of each. It also notes that food pyramids show the transfer of biomass from one trophic level to another.
