Microorganisms, also known as micro organisms, micro-organisms and microbes cause a number of problems. Of course, the most obvious is that they cause disease. Things like bacteria and fungus can spread disease and illness incredibly easy, meaning that people will suffer and have to seek treatment. Microorganisms, or microbes, are also the main reason why food rots. Whilst there are other reasons why food eventually spoils, it is certainly true that microbes cause most of the decay. This is why we have freezers, as freezing the bacteria ensures that it is not able to live and not able to decompose any of the food.
Microbes are often single celled and invisible to the naked eye, but this is not necessarily the rule. Many scientists disagree with each other, but it is certainly true that there are multi-cellular microorganism forms out there, and even kinds of bacteria that are very much visible to the naked eye.
One controversial topic in this particular area of science is whether or not a virus should be classed as a microbe. Viruses are not technically alive as they do not express any of the required characteristics to be classed as a living thing - however, they are indeed incredibly small and they do cause similar problems to other microbes. They cause sickness and illness in humans and animals.
Microbes are also a part of the recycling process which is found in many ecosystems. Given that these small organisms decompose food and other materials, and very little else causes quick decomposition, the soils in many ecosystems would not be able to do without the microbes. Some microbes are an essential part of the nitrogen cycle, too, meaning that they don't all cause problems for us humans. In fact, many microbes live within us and help us with many bodily functions.
