What is the role of decomposers in an ecosystem?

This question was previously asked in
RRB Group D 2025 Question Paper (9-Aug-2026) (Shift 1)
The correct answer is

Break down dead remains of organisms

Decomposers such as bacteria and fungi feed on the dead remains and wastes of plants and animals.

They break down complex organic substances into simple inorganic substances, which return to the soil and are reused by plants, so nutrients are recycled in the ecosystem.

Making organic substances from inorganic ones and converting light energy into chemical energy are functions of producers (green plants) during photosynthesis, not of decomposers.

Hence, the answer is Break down dead remains of organisms.
