As well-nigh microorganisms can fix nitrogen, they are a vital department of the nitrogen cycle, and recent studies indicate that airborne microbes may allow rein a role in precipitation and weather.[5] Microbes are also exploited by people in biotechnology, two in traditional food and beverage preparation, and in mod technologies ground on g enetic engineering. However, pathogenic micr! obes are harmful, since they beleaguer and enhance within other organisms, causing diseases that kill humans, other animals and plants.
