Answer
Brief Explanations:
- Option a: While the nitrogen cycle is crucial (for protein and nucleic acid synthesis), it's incorrect to say it's the "most important" as all cycles are vital.
- Option b: The oxygen cycle is essential (for respiration, combustion, etc.), so claiming it's the "least important" is wrong.
- Option c: Life cannot be sustained without matter cycles (like water, carbon, nitrogen, oxygen cycles which provide necessary substances and maintain balance).
- Option d: All matter cycles (water cycle, carbon cycle, nitrogen cycle, oxygen cycle etc.) work in tandem. For example, plants use carbon dioxide (carbon cycle) and water (water cycle) in photosynthesis, produce oxygen (oxygen cycle), and need nitrogen (nitrogen cycle) for growth. Each cycle is interdependent and equally important for life - sustaining processes.
Answer:
D. All cycles of matter are equally important for life to be sustained.
