AP BIOLOGY

Detailed explanation-1: -Decomposers break down dead and decaying matter, releasing nutrients back to the soil, Arctic tundra decomposers include molds, yeasts, the fungi from lichen, and microorganisms called bacteria.

Detailed explanation-2: -Most decomposers are microscopic organisms, including protozoa and bacteria. Other decomposers are big enough to see without a microscope. They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes.

Detailed explanation-3: -Bacteria are found in the water column. They are eaten by protists (ciliates and microflagellates), other microorganisms found in the water column, which are then eaten by zooplankton.

Detailed explanation-4: -Bacteria is a common decomposer in the arctic ocean. They recycle organism matter and release nutrients into the ecosystem.

Detailed explanation-5: -Decomposers such as bacteria and fungi work overtime when the rains come-water helps them break down waste material quickly. But some desert decomposers operate even in dry times. Take termites. Humans don’t like them because they eat wood-not good if your house becomes a termite snack bar.
