A detritivore is an organism that obtains its nutrition by consuming detritus, which is dead organic matter. This includes fallen leaves, animal carcasses, feces, and other organic waste. Detritivores play a crucial role in ecosystems by breaking down this organic matter, releasing nutrients back into the environment, and contributing to the decomposition process.

Key characteristics of detritivores:

* Heterotrophic: They rely on consuming organic matter produced by other organisms.

* Feed on detritus: They are specialized in consuming dead organic matter rather than living plants or animals.

* Decomposers: Their feeding activities contribute to the breakdown of organic matter and nutrient cycling.

* Essential for ecosystems: They play a vital role in the decomposition process, ensuring the recycling of nutrients and maintaining ecosystem health.

Examples of detritivores:

* Invertebrates: Earthworms, millipedes, snails, slugs, dung beetles, termites, and some species of flies.

* Vertebrates: Some fish, crabs, and vultures.

* Microorganisms: Fungi and bacteria are key decomposers.

Science definition:

Detritivore: An organism that consumes detritus, dead organic matter, and plays a critical role in decomposition and nutrient cycling.

It's important to note that while detritivores are often considered decomposers, they are not the same thing. Decomposers are a broader category that includes all organisms that break down organic matter, including bacteria, fungi, and some detritivores.
