Final answer:

Nitrogen fixation, nitrification, and assimilation are key processes in the nitrogen cycle that enable plants to utilize nitrogen efficiently.


Explanation:

Nitrogen fixation is the process where nitrogen gas is converted into ammonia by nitrogen-fixing bacteria like rhizobia found in legumes. This helps in making nitrogen available for plants to use. Nitrification is the conversion of ammonia into nitrate by nitrifying bacteria, facilitating plant absorption of nitrogen. Assimilation is when plants take up the fixed nitrogen compounds to build proteins and other essential molecules for growth.
