What poses the least threat to desert ecosystems?
A) groundwater depletion
B) overgrazing
C) a nomadic lifestyle
D) irrigation and salinization
Groundwater Depletion
The excessive withdrawal of groundwater resources faster than they can naturally be replenished, leading to a decline in groundwater levels.
Overgrazing
occurs when plants are exposed to intensive grazing for extended periods, impairing plant growth and soil health.
Nomadic Lifestyle
A way of life characterized by moving from one place to another rather than settling permanently in one location, often for reasons such as following seasonal food sources or grazing lands for livestock.

Final Answer :
C
Explanation :
A nomadic lifestyle poses the least threat to desert ecosystems since it involves moving from one place to another to minimize resource depletion and overuse in a particular area. This also helps to avoid overgrazing and disturbance of natural habitats. Groundwater depletion, irrigation, and salinization are major threats to desert ecosystems, which can result in soil degradation, desertification, and loss of biodiversity.
