The sun is the source of all the energy on the earth. Plants are producers; they turn energy from the sun into sugars that animals can use. Insects and other animals eat plants for energy. They are primary consumers. They are herbivores. Secondary consumers are animals that eat other animals for energy. They are called carnivores. Decomposers are organisms that eat dead things for energy.
