B Correct answer
Explanation

Plants are producers, not decomposers. They do not break down organic matter; rather, they contribute organic matter to soil through leaf litter and root death. Fungi, bacteria, and earthworms are all decomposers that break down organic material, recycling nutrients back into the soil.
