Correct answer: B. 2 and 3 only

Decomposers are crucial components of ecosystems, responsible for breaking down dead organic matter. Fungi and bacteria are the primary examples of such organisms, obtaining nutrients by decomposing dead plants and animals. Viruses, while interacting with living organisms, do not perform the role of decomposers in the way that fungi and bacteria do.
