This question was previously asked in
UPTET 2026 Paper 2 Social Studies Question Paper (3-Jul-2026) (Shift 1)
The correct answer is

Decomposers

Decomposers are organisms such as bacteria and fungi that break down the complex organic compounds present in dead plants and animals.

Through this process, complex organic matter is converted into simpler inorganic substances, which are then released back into the soil, water, and air.

This recycling of nutrients by decomposers keeps essential elements such as carbon and nitrogen available for producers to use again, so decomposers are the group responsible for this breakdown.
