    The process of mineralization

    releases:
    A Organic nutrients from detritus Correct Answer Incorrect Answer
    B Inorganic nutrients from detritus Correct Answer Incorrect Answer
    C Organic compounds from soil Correct Answer Incorrect Answer
    D Humus into the food chain Correct Answer Incorrect Answer

    Solution

    Mineralization is the final step in the decomposition process, where microorganisms break down organic matter in detritus into inorganic nutrients like nitrogen (N), phosphorus (P), and sulfur (S), making them available for plant uptake. Steps in Decomposition: (i) Fragmentation – Detritivores break detritus into smaller particles. (ii) Leaching – Water dissolves soluble organic and inorganic nutrients. (iii) Catabolism – Enzymatic breakdown of complex organic compounds. (iv) Humification – Formation of humus (partially decomposed organic matter). (v) Mineralization – Conversion of organic matter into inorganic nutrients by decomposers like bacteria and fungi.
