The process of degradation of humus by some microorganisms and release of inorganic nutrients is known as
Explanation
Decomposition is a vital ecosystem function involving five stages: fragmentation, leaching, catabolism, humification, and mineralization. Humification leads to the accumulation of humus, a dark-colored amorphous substance that is highly resistant to microbial action. Mineralization is the final step where the humus is further degraded by specific microorganisms, resulting in the release of inorganic nutrients (such as CO2, water, and minerals like nitrogen and phosphorus) back into the soil. Among the other options, eutrophication refers to the excessive nutrient enrichment of water bodies, and stratification is the vertical layering of different species within an ecosystem, such as the distinct levels in a tropical rainforest.
