Question

a desert area has many species of cactus and brush as well as birds, snakes, lizards, and rodents. this desert is an example of a dropdown with options: climax community, pioneer species, disturbance, secondary succession.

Explanation:

A climax community is a stable, mature ecological community that has reached a state of equilibrium with its environment. The desert described has a variety of species (cacti, brush, birds, snakes, lizards, rodents) that represent a stable, self - sustaining community. Pioneer species are the first species to colonize a barren area, which is not the case here as the desert has a diverse community. Disturbance refers to an event that disrupts an ecosystem, not the ecosystem itself. Secondary succession is the process of ecological recovery after a disturbance, but the question is about what the desert is an example of, not a process. So the desert is a climax community.

Answer:

A. climax community
