Life can exist without microorganisms or not?write an essay
Answers
Answer:
Explanation:
Microbes sustain life on this planet because of their myriad associations and biogeochemical processes. Nonetheless, their roles are not necessarily irreproducible. When you next hear someone claim that we cannot live without microorganisms, it would be appropriate to ask them to qualify the statement. Would we still be able to eat and digest food? Yes. Would life be extinguished in the absence of Bacteria and Archaea or in a world without any microbes? Not immediately, not all life, and potentially not for a long time.
In short, we argue that humans could get by without microbes just fine, for a few days.* Although the quality of life on this planet would become incomprehensibly bad, life as an entity would endure.
* If we do include mitochondria and chloroplasts as Bacteria, as we should, then the impact would be immediate—most eukaryotes would be dead in a minute.
Answer:
But as long as humans can't live without carbon, nitrogen, protection from disease and the ability to fully digest their food, they can't live without bacteria, said Anne Maczulak, a microbiologist and author of the book "Allies and Enemies: How the World Depends on Bacteria" (FT Press, 2010).A world without microbes seems at first like a utopia without bacterial infections, mildew, or mold. ... We wouldn't be able to digest our food properly without our gut bacteria. Crops around the world would start to die without the nutrients generated by microbes.Microscopic creatures—including bacteria, fungi and viruses—can make you ill. But what you may not realize is that trillions of microbes are living in and on your body right now. Most don't harm you at all. In fact, they help you digest food, protect against infection and even maintain your reproductive health.
