The Chihuahuan Desert of the United States and Mexico may be the most biologically diverse deser in the world. Extensive grazing has caused the flora and soil of this ecosystem to become unstable. How has biodiversity affected the sustainability of this ecosystem? A Biodiversity has put this ecosystem at risk of being less sustainable in the future. B Biodiversity has not changed this ecosystem's level of sustainability.
C Biodiversity has prevented this ecosystem from being sustainable.
D Biodiversity has helped this ecosystem remain sustainable.

A

Explanation:

Biodiversity has this ecosystem at risk of being less sustainable in the future, because it exposes the land to drought and other adverse conditions not supporting biodiversity in the future.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
