Question

What would happen without nitrogen fixing bacteria?

Answer 1

Nitrogen cycle:

1. The nitrogen cycle is the process of nitrification & denitrification which regulates nitrogen levels in the atmosphere.
2. Nitrogen is not returned to the atmosphere without denitrification, therefore it is contained & not recycled.
3. Excess nitrogen is bound and is usually not available for biological processes to take place.
4. Nitrogen will usually not be made accessible to plants in usable forms (ammonia and nitrate), limiting their growth and development.
5. Because plants are the main producers, this can also have an impact on the entire food chain.
6. Free nitrogen is then transformed into nucleotides, amino acids, & other nitrogenous substances through fixation.
7. These important compounds, which are essential for the functional and structural growth of entities, will usually not be created if the fixation and hence denitrification does not occur.
8. Examples of nitrogen-fixing bacteria include Nostoc, Anabaena, Nitrosomonas, Nitrobacter, etc.
