Role of bacteria

Why is it so important?

How do these bacteria fight off viruses?

When a virus enters the coccolithophore, a unicelluar and eukaryotic organism under the kingdom Protista, they release a chemical signal and the other cells change their DNA and tend to result in having jagged scales in place of plates. The coccolithophore shuts down in order to prevent the spreading of the virus.

Why is this "war" so important?

When the coccolithophore blossoms, they take in carbon dioxide and release oxygen. They are responsible for half of the oxygen in which humans breathe. This battle is so important due to the fact that humans would not be able to survive without this "war".

Bacteria in soil

Soil bacteria, rhizobia, interact with legume roots in order to produce specialized structures called nodules in which nitrogen fixation occurs. It is important because this process leads to the reduction of atmospheric nitrogen to ammonia in terms of the enzyme nitrogenase. Using rhizobia is a natural and eco-friendly way to fertilize plants unlike chemical fertilization which uses a non-renewable resource like natural gas. The plant benefits from using a never-ending source of nitrogen from the atmosphere rough symbiotic nitrogen fixation. This also helps soil fertility because the plant root system leaves behind some of the biologically-available nitrogen. The plant obtains ammonia and bacteria obtain carbon compounds generated through photosynthesis, as well as a protected niche in which to grow, representing a symbiotic relationship.

Bacteria in aquatic habitats

Bacteria is found in literally almost every place possible. Cyanobacteria is a type of bacteria that is categorized under the kingdom of Eubacteria which is very important in it's environment. Cyanobacteria is often found in aquatic habitats and is typically found in freshwater rather than saltwater habitats. For example, a clear body of water can often have areas that turn into blue-green cyanobacteria blooms. These blooms can often produce nerve and liver toxins; Microcystins and Anatoxin-A. Microcystins are a group of toxins caused by cyanobacteria.
