A
Scavengers
B
Omnivores
C
Decomposers
D
Herbivores
Explanation: 

Detailed explanation-1: -They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes. Fungi are important decomposers, especially in forests.

Detailed explanation-2: -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-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.

Detailed explanation-4: -Saprotrophs or decomposers include microbes such as bacteria and fungi that decompose the dead remains of plants and animals, to extract nutrients and energy.
