Multiple Choice

Which process is correctly paired with its cycle?

Explanation:
Matching processes to the cycle they belong to is being tested here. Nitrogen fixation is the conversion of atmospheric N2 into ammonia, a form that organisms can use, and it’s a defining step of the nitrogen cycle. Photosynthesis uses carbon dioxide to build organic molecules, tying it to the carbon cycle rather than the nitrogen cycle. Osmosis is the passive movement of water across a membrane and is not part of a biochemical cycle. So the pairing that fits is nitrogen fixation with the nitrogen cycle.
