Decomposition and decay are two closely related processes that are both important parts of the cycle of life.

Decomposition is the breakdown of organic material (living or once living) into smaller parts. For example, when a plant or animal dies, bacteria and other organisms will break the material down and return the nutrients to the soil or air. The process releases energy into the environment, which is then used by other organisms. Decomposition is essential for the recycling of nutrients and for the continuation of life.

Decay is a subset of decomposition. It is the breakdown of dead material from organisms that are no longer alive. It is a natural process that begins shortly after death. Decay also helps to release energy and nutrients back into the environment. For example, when wood decays, it releases carbon dioxide and other gases and chemicals. This helps to create the soil that plants need to grow.

The two processes differ slightly in the way they break down organic material. Decomposition is the breakdown of organic material by living organisms, while decay is the breakdown of organic material by non-living organisms. Decay is also seen as a form of decomposition that usually occurs faster.

Both decomposition and decay are important to the environment and play a vital role in the cycle of life. They are essential to the recycling of nutrients and energy and allow life to continue. Without them, Earth’s ecosystems would not exist.
