Detailed explanation-1: -Consumers constitute the upper trophic levels. Unlike producers, they cannot make their own food. To get energy, they eat plants or other animals, while some eat both. Scientists distinguish between several kinds of consumers.
Detailed explanation-2: -Consumers, or heterotrophs, get organic molecules by eating other organisms. A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
Detailed explanation-3: -Decomposers are an important part of a food chain because they break down dead plants and animals and also the waste of other organisms, thus, keeping up a continuous flow of nutrients for the primary producers.
Detailed explanation-4: -Producers make food for themselves and other living things. Decomposers break down dead plants and animals into component parts. Grazers feed on living organisms without killing them. Predators, like lions, capture and kill animals for food.
