Microbial ecology is about learning about the different types of microscopic creatures (called microbes) that live in different places in the world. Microbes are really small, so you need special tools called microscopes to see them. Scientists use microbial ecology to study how different kinds of microbes live and interact with each other, and how they affect the environment around them. They look at things like how they grow, how they move, what they eat, and how they work together in order to survive. By understanding the microbial ecology of different environments, scientists can figure out how to keep the environment healthy and how to use the microbes to make things like food and medicine.
