Nitrogen fixation makes nitrogen gas useful to crops.

true or false

True

Explanation:

The nitrogen fixation is a process that involves conversion of atmospheric nitrogen to nitrates in the soil. This process is mainly performed by nitrogen-fixing bacteria present in the soil.

The nitrogen fixation is important for plants and animals. The nitrogen present in the atmosphere cannot be used directly by animals and plants. The nitrogen is main constituent of chlorophyll that is required for the process of photosynthesis and for amino acids that synthesize proteins. Thus, Nitrogen fixation makes nitrogen gas useful to crops.
