In warm climates, what happens to organic matter in soil?

In warm climates, organic matter in the soil decomposes rapidly due to higher temperatures and increased microbial activity. Microorganisms, such as bacteria and fungi, thrive in warmer conditions and are key players in the decomposition process. The warmth enhances the metabolic rates of these organisms, leading to faster breakdown of organic materials like dead plants and decomposing animals.

Additionally, warm temperatures often lead to increased moisture levels, especially in regions with ample rainfall, which further promotes the activity of decomposers. As a result, nutrients are quickly released back into the soil, making them available for plants and enhancing soil fertility. This relationship between temperature, moisture, and biological activity explains why organic matter does not remain unchanged or decompose slowly in warm climates. It is the accelerated breakdown that plays a crucial role in nutrient cycling and overall ecosystem productivity in these regions.
