Question

The process of mineralisation by microbes helps in the release of ______.

Options

• organic nutrients from humus

• inorganic nutrients from humus

• both organic and inorganic nutrients from detritus

• inorganic nutrients from detritus and formation of humus

Answer 1

The process of mineralisation by microbes helps in the release of inorganic nutrients from humus.

Explanation:

During mineralisation, microbes further degrade humus, converting complex organic matter into simpler inorganic nutrients such as nitrates, phosphates, and sulfates, which plants can readily absorb and use for growth. This process is crucial for nutrient cycling in ecosystems and maintaining soil fertility.
