Usage

What is a detritivore? A detritivore is an organism that eats dead or decaying plants or animals as food. Detritivores include microorganisms such as bacteria and larger organisms such as fungi, insects, worms, and some crustaceans.Detritivore is a combination of the word detritus and the suffix -vore. Detritus means waste or debris—in this case, dead plants and animals. The suffix -vore means “one that eats,” as seen in herbivore (plant eater) and carnivore (meat eater). So a detritivore eats dead plants and animals. Animals classified as scavengers also eat dead matter, but on a larger scale.Detritivores are an essential part of the food chain because they help to break down dead plant or animal matter. This returns essential nutrients to the ecosystem and helps to prevent a buildup of dead or rotting material that could spread disease and have other negative consequences.
