Discuss Decomposition.

Introduction

• Soil formation is a complex process involving the breakdown of rocks, sediments, and organic matter.
• Decomposition is a key component of this process, where organic material transforms into soil.

Weathering

• Weathering is the physical and chemical breakdown of rocks and sediments.
• Physical weathering includes processes like freezing and thawing, which break rocks into smaller pieces.
• Chemical weathering involves reactions that alter the mineral composition of rocks.

Decomposition

• Decomposition is the breakdown of organic matter (such as leaves, plants, and dead animals) into simpler substances.
• It is primarily driven by microorganisms like bacteria and fungi.
• Decomposers break down organic matter into humus, a dark, organic-rich material.

Importance of Decomposition

• Decomposition enriches the soil with nutrients and organic material.
• It improves soil structure, aeration, and water-holding capacity.
• Decomposition also contributes to the carbon cycle, releasing carbon dioxide back into the atmosphere.

Factors Affecting Decomposition

• Temperature: Higher temperatures accelerate decomposition.
• Moisture: Adequate moisture is essential for decomposition.
• Oxygen: Decomposers require oxygen for their metabolic processes.

Summary

• Soil formation involves the breakdown of rocks, sediments, and organic matter.
• Decomposition, driven by microorganisms, transforms organic material into humus, enriching the soil.
• Factors like temperature, moisture, and oxygen influence the rate of decomposition.
