What term refers to non-living organic matter, such as dead leaves and animals?

• A. Detritus
• B. Biomass
• C. Soil
• D. Humus

Answer: (A)

Detritus refers specifically to non-living organic matter that has come from the decomposition of plants and animals. It encompasses various materials, including dead leaves, animal remains, and any organic debris that is in the process of breaking down. This term is particularly significant in ecological studies, as detritus plays a crucial role in nutrient cycling and supports various decomposer organisms like fungi and bacteria, which recycle nutrients back into the ecosystem. Biomass, on the other hand, refers to the total mass of living organisms in a given area or volume, making it distinct from non-living matter. Soil is the medium in which many organisms live and grow, composed of minerals, organic matter, water, and air. Humus is a specific type of organic matter resulting from the decomposition of plant and animal material, contributing to soil fertility, but it is not the broader term that encompasses all non-living organic matter.
