What are decomposers?
A
Organisms that get their nergy by breaking down waste and dead organims
B
Organisms that eat other living organisms
C
Organisms that eat plants
D
Organisms that make their own food
Explanation: 

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: -Decomposers (Figure below) get nutrients and energy by breaking down dead organisms and animal wastes. Through this process, decomposers release nutrients, such as carbon and nitrogen, back into the environment. These nutrients are recycled back into the ecosystem so that the producers can use them.

Detailed explanation-3: -Decomposers act on the dead matter, e.g. by secreting the enzymes and digesting the matter externally. Saprotrophs contribute to the decomposition process by extracellular digestion, i.e., they digest dead matter externally by secreting enzymes and then absorbing the nutrients.
