Give reasons why decomposition is faster in tropical regions.

Decomposition occurs faster in tropical regions due to favorable environmental conditions that enhance the activity of decomposers.

One of the main reasons is high temperature. Warm conditions accelerate the metabolic and enzymatic activities of microorganisms such as bacteria and fungi, leading to rapid breakdown of organic matter.

High moisture levels in tropical regions also support microbial growth and activity. Adequate water availability helps in the efficient functioning of decomposers and facilitates chemical reactions involved in decomposition.

Tropical regions also have a rich diversity and abundance of decomposers and detritivores, including insects, earthworms, and microorganisms, which speed up both physical and chemical breakdown processes.

Additionally, the continuous availability of organic matter due to dense vegetation ensures that decomposition is an ongoing and active process.

These combined factors make decomposition significantly faster in tropical climates compared to colder or drier regions.
