explain why the food chain is represented as a pyramid
Food chains, pyramids of numbers and pyramids of biomass are all ways of showing how energy is passed on from one organism to another. Biomass is the food available for the next trophic level (feeding level) in a food chain. Biomass is used as a source of renewable energy to reduce our dependence on fossil fuels.he pyramid of numbers usually shows that the number of organisms at each trophic level gets smaller towards the top. This particular case is an exception â one tree provides food for many caterpillars.
