Decay

Decay is a natural process that involves the breakdown or decomposition of organic matter. This process is essential in the cycle of life as it allows for the recycling of materials and the continuation of life. Decay can refer to various processes in different fields such as physics, dentistry, and biology.

Physics

In physics, decay specifically refers to the process by which an unstable atomic nucleus loses energy by radiation. This is known as radioactive decay. It is a random process at the level of single atoms, in that, according to quantum theory, it is impossible to predict when a particular atom will decay.

Dentistry

In dentistry, decay, also known as dental caries or cavities, is the breakdown of teeth due to acids made by bacteria. The cavities may be a number of different colors from yellow to black. Symptoms may include pain and difficulty with eating.

Biology

In biology, decay refers to the process by which a dead organic substance is broken down into simpler forms of matter. This process is essential for the recycling of nutrients in ecosystems and is carried out by decomposers, which include bacteria and fungi.
