In an ecosystem, the decomposers perform an important role. Select the option indicating the role of decomposers.

Options

• Convert inorganic materials to simpler forms

• Break down complex organic substances to simple inorganic substances.

• Break down inorganic substances into organic substances.

• Do not act on organic compounds.

Answer 1

Break down complex organic substances to simple inorganic substances.

Explanation:

• Decomposers (mainly bacteria and fungi) feed on dead plants and animals and break complex organic molecules into simpler inorganic forms.
• This process (mineralization) returns nutrients like nitrogen, phosphorus and carbon to the soil and atmosphere, making them available for producers.
• By recycling nutrients, decomposers maintain ecosystem nutrient cycles and support continued productivity.
