What are 5 positive things ofbacteria?

Answer 1

As some bacteria are harmful, there are some good things about bacteria in general.

1. If it weren't for bacteria, we wouldn't be here.

All organisms on earth can trace their roots back to one group of organisms -primitive precambrian bacteria. If it weren't for those, complex life (like us) wouldn't be able to exist.

2. Bacteria aid in the digestive process.

3. Cheese, yogurt, and many other foods would not exist.

4. If it weren't for bacteria, the corpses would just pile up.

Most bacteria are decomposers, meaning that they utilize dead or decaying matter for their food source. Without them, dead bodies would just sit there and not go away. There wouldn't be enough soil in the world to bury them all -in fact, without bacteria, there would be no soil -which takes us to our fifth positive aspect of bacteria.

5. Most people say that plants are the bottom of the food chain. The base of all life. They're wrong. In a terrestrial ecosystem, a plant would need soil for nutrients. Without bacteria, soil could not exist. In an aquatic ecosystem, such as an ocean, big fish need to eat little fish who prey on krill who eat plankton. Most people think it stops there. While some plankton are autotrophs (phytoplankton), the heterotrophic ones (zooplankton) find their metabolic sustenance from dead matter or -you guessed it- bacteria.
