What if there was no micro organisms on earth what will happen?

Answer 1

Microorganisms are the basis of many processes that sustain life. If all the microorganisms on earth were to suddenly disappear, then the nitrogen cycle would be immediately disrupted, as nitrification would no longer occur. Many oxygen generating bacteria would be gone. The human body itself contains many symbiotic microorganisms, although the actual effect their disappearance might cause is unclear.

Answer 2

If all the microorganisms disappeared, then all of the animals that ate those microorganisms would start to die, or if those microorganisms were decomposers, then dead animals and plants would pile up.

Answer 3

We would not exist and nothing would be as it is. There would be nothing in existence.

Answer 4

We will all gonna be in trouble if these microbes are destroyed because microbes decomposes us and break us down.They will never keep us from accumulating any more.

Answer 5

Microorganisms are an essential part of the world's food web. If they disappeared, likely all life would too. For instance many are decomposers, responsible for recycling nutrients.
