Answers
Answer:
Microbes run the world. It's that simple.” (Committee on Metagenomics, 2007 blue right-pointing triangle). Microbial communities make the essential elements of oxygen, carbon, nitrogen, and sulfur available for other life on our planet. Without microbial decomposer communities, life would be smothered in dead organisms. Microorganisms also carry out almost half of the photosynthesis on our planet, increasing oxygen levels and lowering carbon dioxide (Pedros-Alio, 2006 blue right-pointing triangle). Both animals and plants are closely associated with microbial communities that make nutrients more available, provide protection from diseases, make essential vitamins, or a combination. For example, each human body hosts 10 microorganisms for every human cell, and these microbes contribute to digestion, produce vitamin K, promote development of the immune system, and detoxify harmful chemicals. And, of course, microbes are essential to making many foods we enjoy, such as bread, cheese, and wine.
