Bacteria and microbes are tiny organisms that exist everywhere on Earth. Some bacteria are harmful, causing diseases, while others are beneficial and essential for processes like digestion. Microbes can be found in extreme environments, such as hot springs or deep in the ocean, where life thrives under unusual conditions.
There are several different types of bacteria and microbes, including archaea, bacteria, and fungi. Each plays a vital role in its environment, from breaking down organic matter to helping with food production. Understanding the diverse types of bacteria and microbes is crucial for fields such as medicine, biotechnology, and environmental science.
