Which term best describes an animal that eats dead and decaying meat?

producer

predator

decomposer

herbivore

An animal that eats dead and decaying meat is called a decomposer.

Producers are organisms like plants that create and produce energy, herbivores are plant eaters, and predators are meat eaters. This means that decomposers are the organisms that eat dead and decaying meat. Hope that helps. :)
