AP BIOLOGY

Detailed explanation-1: -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-2: -Bacillus subtilis and Pseudomonas fluorescens are examples of decomposer bacteria.

Detailed explanation-3: -Decomposers (fungi, bacteria, invertebrates such as worms and insects) have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting.

Detailed explanation-4: -Microorganisms like bacteria and fungi break down organic remains of plants/animals and add them to the soil. So, they are called decomposers.
