What is the difference between decomposers and scavengers?

Decomposers and scavengers both play roles in breaking down dead organisms, but they differ in how they carry out this process.

Decomposers are microorganisms such as bacteria and fungi that chemically break down dead organic matter into simpler substances. They release enzymes that convert complex materials into nutrients like carbon dioxide, water, and minerals, which are returned to the environment.

Scavengers, on the other hand, are animals such as vultures, hyenas, and crows that feed on dead organisms. They physically consume and break down large pieces of organic matter into smaller fragments but do not convert them into basic nutrients at the chemical level.

In simple terms, scavengers initiate the breakdown by consuming dead matter, while decomposers complete the process by converting it into reusable nutrients.
