A food chains shows what eats what in a habitat.
Pyramids of biomass reveal the mass of living material at each stage in a chain. The amount of material and energy decreases from one stage to the next.
Radiation from the sun is the ultimate source of energy for most communities of living things. Green plants and algae absorb some of the suns light energy and transfer this energy into chemical energy.
This happns during photosynthsis and the chemical energy is stored in the substances and then passed onto the consumers who get all the energy and biomass from eating the organisms.
