Microbes are crucial to the survival of ecosystems.In fact,if there was no microbes there would be no ecosystems or life at all.Microbes eat dead things (the process of decomposition), which reduces waste,as an effect of this ecosystems can grow and thrive because of more space,which means humans benefit from lusher wildlife that reduces carbon dioxide.Microbes also help in making food for plants.(photosynthesis),which allows plants to stay alive longer.Probably the most important thing that microbes do in ecosystems is recycling oxygen adn nitrogen.without this our world would be over-polluted with gases, and we would eventually die form the toxic fumes.The microbes soak up the nitrogen and carbon dioxide and redistribute it as a friendly gas.This process is like the the process that trees go through.The microbes also process minerals which they hardea dn break down.As the microbes do this new minerals are formed.So without these microbes there is a limited amount of minerals and no life.
As I said before,they're is trillions of microbes in your body,ounumbering blood cells 9 to 1.As I'm saying this I'm realizing how i used to think there was a lot of blood cells,but compared to the amount of microbes its nothing!Most of them being bacteria,live in the stomach where they reduce acid levels.Helpful bacteria help to defend your body from archea and protozoa.(Both are parasites)Microbes in your body also help t send siganls to your brain when you're hungry or full.Doing this really makes me realize how important microbes are to anything that is living.In other words no microbes equals no life.
