7.EC.5B.2 Develop and use models (food webs and energy pyramids) to exemplify how the transfer of energy in an ecosystem supports the concept that energy is conserved.
Plants harness the energy from the sun and turn it into a useable form for all organisms in an ecosystem. Consumers eat the plants or other organisms to gain energy. Decomposers break down dead organisms (both plants and animals) back into useable form.
