Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Decomposers – Bacteria.
The correctly matched option is Decomposers – Bacteria. Decomposers, including bacteria, play a critical role in breaking down organic matter from dead plants and animals, recycling nutrients back into the ecosystem. The other options are incorrectly matched: herbivores are primary consumers (not secondary), omnivores consume both plants and animals (not just green plants), and carnivores are secondary or tertiary consumers (not primary consumers).
