![]() They are involved in many nutrient cycles in ecosystems such as nitrogen cycle, carbon cycle, and phosphorus cycle. Most soil bacteria also serve as decomposers. Insects such as dung beetle, red weaver ants, and flesh fly are the examples of scavengers as well. Hyenas, coyotes, and polar bears are mammal scavengers. Some birds such as vultures and crow are also scavengers. Scavengers and other carnivores belong to the third trophic level of a food web. But, scavengers do not hunt and kill prey. Most scavengers are carnivores, who feed on dead animals. The major role of scavengers in an ecosystem is to keep the ecosystem free of dead bodies. It can be also called a detritivore since a scavenger relies on the waste materials. Scavenger is an animal that feeds on dead plants, animals or carrion. Key Terms: Carnivores, Carrion, Dead Animals, Dead Plants, Decomposer, Detritivores, Ecosystem, Saprotrophs, Scavenger What is a Scavenger What is the Difference Between Scavenger and Decomposer What are the Similarities Between Scavenger and DecomposerĤ. – Definition, Role in the Ecosystem, Examplesģ. Both these types of organisms recycle nutrients in the ecosystems. ![]() The biological term for decomposers is saprotrophs. Earthworms and bacteria are also decomposers. Scavengers can be animals such as birds, crabs, insects, and worms. The main difference between scavenger and decomposer is that scavenger consumes dead plants, animals or carrion to break down the organic materials into small particles whereas decomposer consumes the small particles produced by the scavengers. Scavenger and decomposer are two types of organisms that are responsible for the recycling of organic matter. Main Difference – Scavenger vs Decomposer
