Question

The Chihuahuan Desert of the United States and Mexico may be the most biologically diverse desert

Answer 1

Answer: C Biodiversity has prevented this ecosystem from being sustainable.

Explanation:

The extensive grazing by the organisms in the Chihuahuan Desert which has made the ecosystem unstable has made the ecosystem incapable of sustaining the organisms that depend on it.

This is because the extensive grazing means that the ecosystem in the desert which comprises of the flora has seen its resources being overused and can now no longer support the organisms in it.
