Answer:
Nitrogen-fixing bacteria
Explanation:
These type of bacteria living in the soil or symbiotic interaction with root plants has the ability to transform the atmospheric nitrogen (N2) into ammonia (NH3), in this form many organisms like plants can metabolise. Bacterial genera like <em>Azotobacter </em>spp.<em>, Rhizobium </em>spp.<em>, Azospirilum </em>spp.<em>,</em> etc. can make the transformation of nitrogen by specialized enzymes called nitrogenases.
Fish definitely have a central nervous system!

Their brains even have the same parts as the human brain! For example, they also have a cerebellums
That is false, the right side receives DEoxygenated blood.
So that they could adapt to there habitat
All living creatures are classified into systems and sub-systems based on their similar characteristics. They are divided from bigger groups into smaller groups based on the detail of their similarities i.e. how they look, move, reproduce and how they relate to each other. A practical way of understanding the classification of living organisms is that organisms are linked to other similar organisms via family trees. The classification of all living creatures includes at least four levels: order, families, genus and species.
