Which term denotes the natural environment that supports plant life and is made up of mineral particles and organic matter?

• A. Soil
• B. Desert Pavement
• C. Karst Topography
• D. Glacier

Answer: (A)

Soil is the natural environment that supports plant life because it serves as the growing medium where roots anchor, water and nutrients are stored, and air moves through for root respiration. It is formed from mineral particles such as sand, silt, and clay combined with organic matter from decomposed plants and animals, which creates a porous, nutrient-rich matrix capable of holding water while letting roots grow and access oxygen. This combination is what makes soil fertile and capable of supporting diverse plant life. The other terms describe different landforms or materials that do not function as the primary growing medium for plants. Desert pavement refers to a rocky desert surface with little soil development. Karst topography describes limestone landscapes shaped by dissolution, forming features like caves and sinkholes. A glacier is a large body of compressed ice that erodes and reshapes terrain rather than serving as a plant-growing medium.
