Which component is essential for maintaining soil biodiversity?

• A. Organic matter
• B. Heavy machinery
• C. Monoculture planting
• D. Synthetic fertilizers

Answer: (A)

Maintaining soil biodiversity is crucial for healthy ecosystems, and organic matter plays a vital role in this aspect. Organic matter, which includes decomposed plant and animal materials, provides nutrients that are essential for a wide range of soil organisms. It serves as a food source for beneficial microorganisms such as bacteria and fungi, which in turn support the growth of other organisms like earthworms and insects. This complex web of life contributes to soil health by enhancing nutrient cycling, improving soil structure, and increasing water retention.

Furthermore, organic matter also helps to buffer the soil against chemical changes and supports the presence of various plant species, promoting a diverse and resilient ecosystem. In contrast, heavy machinery, monoculture planting, and synthetic fertilizers often lead to soil compaction, reduced diversity, and depletion of organic material, which are detrimental to soil biodiversity. Therefore, organic matter is essential for fostering a vibrant and diverse soil ecosystem.
