Microorganisms are tiny living things that you can’t see with your eyes. They are so small that you need a microscope to see them. They are found everywhere, in the air, soil, water, and even inside our bodies. Some microorganisms are good for us, like the ones that help us digest food. Others can make us sick, like bacteria that cause colds and the flu.
Microorganisms can be different shapes and sizes. Some are round, some are long and thin, and others look like little balls with tails. They can also be different colors, like red, green, or blue. They can live in many different places, like in the soil, on plants and animals, and even inside our bodies.
Microorganisms can reproduce quickly. This means that if one microorganism starts to grow, it can make many new microorganisms very quickly. Some microorganisms can also change into different forms to survive in different conditions. Some can survive in very cold places, while others can live in very hot places.
It’s interesting to know that microorganisms play an important role in our lives. They help us keep healthy and also help the environment. For example, some microorganisms help to break down dead plants and animals, which helps to make soil for new plants to grow. And some microorganisms help make food like cheese and yogurt.
