CONSUMERS THAT EAT AND BREAK DOWN DEAD STUFF

DETRITIVORES- examples include worms, millipedes, beetles and many more.

Detritivores are organisms that survive by consuming decaying organic material, known as detritus. They are typically animals, although some fungi are sometimes classed as detritivores. These organisms play a vital role in a variety of different ecosystems, helping to break down dead matter and release the nutrients stored within it for use my other organims.

In ecology, the terms “detritivore” and “decomposer” are often used interchangeably. These two types of organism do play similar roles in the ecosystem, but they are not exactly identical. Decomposers, rather than ingesting dead organic matter as detritivores do, absorb nutrients on a molecular scale. Similarly, although scavengers play a similar role and some ecologists may include the two types of organism in a discussion for the sake of simplicity, scavengers and detritivores operate on a different scale, with scavengers generally being larger organisms which consume larger amounts of organic matter. A detritivore might feed on the droppings of scavengers or on the parts of carcasses left behind.
