LIFE SCIENCE

Detailed explanation-1: -A group of consumers called the detritivores link all of the trophic levels. Detritivores obtain energy from detritus. Detritus is nonliving organic material, including the remains of dead organisms, leaves, and feces. Because of how they get energy, detritivores are sometimes called decomposers.

Detailed explanation-2: -Typical detritivorous animals include millipedes, springtails, woodlice, dung flies, slugs, many terrestrial worms, sea stars, sea cucumbers, fiddler crabs, and some sedentary polychaetes such as worms of the family Terebellidae.

Detailed explanation-3: -Examples of detritivores include millipedes, woodlice, dung flies, many terrestrial worms and burying beetles. By consuming dead organic matter they speed up decomposition by increasing the surface area available to saprophytic bacteria.
