Energy in an Ecosystem bacteria earthworms mushrooms Sun Energy Cycle The energy cycle within an ecosystem, determines which populations survive and which die. All living things need energy. Ultimately, the Sun is the source of all energy in an ecosystem. Energy flows from the Sun, to producers, then to consumers and finally to decomposers. Producers, Consumers & Decomposers The living organisms in an ecosystem can be divided into three groups: producers, consumers and decomposers. Producers are living things that make their own food using light energy from the Sun. Consumers are animals that get their energy by eating other organisms. Decomposers are organisms that get their energy by breaking down dead plant and animal matter. Examples include mushrooms, bacteria and earthworms. prairie dogs coyote ferret grasshopper rabbit
