Are microbes helpful or harmful

Answer 1

will you be my freind

Microbes are not necessarily dangerous. You have trillions of them on your body, and in your digestive tract all the time and all of them are harmless. There are only a small number that are harmful.

Answer 2

microorganisms are, by definition, small living things.

All living things need a source of food to live, and each kind of micro-organism gets/ use its food differently from another. Thus some might be harmful, and others might not.

A single micro-organism might not be enough to "harm" but all micro-organisms live by the billions/trilllions. When you got an army of them, then they can cause a significant change on other organisms (smaller or way bigger than them).

Micro-organisms can caused a distortion in the food chain (either by eating certain species or unintentionally killing other organisms), and affect a whole ecosystem because of that. IN that way, they can become harmful.

IN humans, there are many micro-organisms that live on or inside us. Most of them are harmless, they can be in any case, beneficial. There are a few species, though, that can cause disease, and thus be harmful to us.

Answer 3

The relationship of microbes to human kind is as old as the existence of human beings. Whether microbes are harmful or beneficial depends on the type of the microbe and their work. The basic work of microbes is to play a role of "decomposers" in our food chain or food cycle, as well as to help break down organic wastes. They work to aid in removing the waste and decaying materials from the Earth. Many microbes help in photosynthesis and also fix nitrogen in the soils for plants which ultimately helps better growth of plants. Some also help in the food and alcoholic drink industries. Microbes work in the fermentation process to create certain food products and alcoholic products. These are only a few of the ways that microbes are beneficial to mankind and the Earth. Nevertheless, many are also harmful as they cause disease in human and other organisms. These illnesses can often be fatal and contagious, even endemic, so, producing disease is an example of how they are harmful to mankind as well as beneficial.
