Decomposition is a vital ecological process driven by microorganisms such as bacteria, fungi, and molds, which break down dead organic matter into simpler compounds. This process recycles nutrients, supports plant growth, and is crucial for ecosystem balance. Microorganisms also play a significant role in food spoilage, leading to potential health risks. Understanding and preventing decomposition is key to food safety and resource conservation.
