The correct answer would be bacteria.

Nitrogen-fixing bacteria are the bacteria which are able to fix atmospheric nitrogen into the compounds which can be used by the plants.

There are mainly two types of bacteria which perform this function:  

Nitrogen is one of the important elements for life. Nitrogen is present in DNA and proteins. It’s also a component of (water, chlorophyll, air) in plants, a pigment that’s critical for photosynthesis. Although nitrogen is present in the air, it can’t be consumed directly. It’s converted into usable form by     (bacteria, animals, plants).

1. chlorophyll

2. bacteria

Explanation:

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
