Consumer in the food chain is a living organism that eats organic matter from different people. The consumer is heterotroph and the producer is autotroph. Both are organisms that derive their energy from other organisms. The four types of consumers in ecology are herbivores, carnivores, omnivores, and decaying animals. Animal food determines where it falls into the food chain, the sequence of organisms that provide energy and nutrients to other organisms. Each food chain contains several trophic levels, which explain the role of the organism in the energy transfer to the ecosystem. Herbivores are first-time buyers, meaning they live on the second trophic level and consume producers.


Herbivores: A herbivore is a plant-eating animal. Weed-eating animals vary in size from small, such as bedbugs, to large ones, such as giraffes. Animals that eat vegetation have a variety of body parts that are particularly prominent in their diet. Many herbivorous animals have large, flat pillars that can withstand powerful vegetation. In addition, herbivores often have large stomach chambers and a special digestive system. For example, cows have four chambered stomach. The cow’s diet first passes through two chambers in the stomach before returning to the mouth to chew more. This recovered food is called cud. When the cow chews and chews, it passes through the third and fourth chambers of the stomach to be digested.

Carnivores: Carnivores are a major part of the food web, which eats other organisms in the wild. Organisms on the web of food are collected in trophic, or nutritious, levels. There are three levels of trophic. Autotrophs, the organisms that produce their own food, are the first trophic level. These include plants and algae. Carnivores and other living animal, are second-
tiered trophic, are the third trophic level. Omnivores, which feed on a wide variety of living things from plants to animals to fungi, are the third trophic level.

Omnivore: An omnivore is a carnivorous animal. Omnivores have evolved various traits to help them eat both plants and animals. Omnivores play an important role in the food chain, the sequence of organisms that produce energy and nutrients from other organisms. The whole food chain contains several trophic levels, which explain the role of living organisms in the ecosystem. Omnivores usually occupy the third trophic level near carnivorous animals. Omnivores have adapted to a variety of features to help them consume both plants and animals. Many omnivores, like humans, have a mixture of sharp teeth and flat molars. However, some carnivorous animals, such as chickens, have no teeth and swallow their whole food. Typically, omnivores have a chamber with one or more chambers and a special digestive tract.

Decomposers: Decomposers are living organisms that dispose of dead or decaying matter; they make rot, a process that can only happen to certain kingdoms, like fungi. Like herbivores and predators, decaying organisms are heterotrophic, meaning that they use organic substrates for energy, carbon, and nutrients to grow and develop. Although the terms decomposer and detritivore are commonly used interchangeably, detritivores swallow and digest dead matter internally, while decomposers absorb nutrients directly through external chemicals and biological processes. Therefore, invertebrates such as worms, wood aphids, and sea cucumbers are deadly they do not rot, as they must eat nutrients, they cannot be absorbed.
