Answer 1

The correct answer is: The nitrogen cycle occurs in terrestrial and aquatic ecosystems.

Explanation: The nitrogen cycle operates in soils, freshwater, and marine environments (and the atmosphere and organisms), moving nitrogen through biological, chemical, and physical processes. The other options are false — the cycle is essential for life and existed long before humans, and it is not limited to warm terrestrial ecosystems.
