Final answer:
A cactus plant, a snake, and a hawk can be members of the same community, while they belong to different species.
Step-by-step explanation:
In biology, a cactus plant, a snake, and a hawk can be members of the same community. A community is a group of different species that occupy the same area and interact with each other. The cactus plant, snake, and hawk may all live in the same desert ecosystem, with the cactus providing shelter and food for insects, which then attract the snake, and the snake serving as prey for the hawk. This illustrates how different organisms can coexist and depend on each other in a community.
On the other hand, a species refers to a group of organisms that share similar characteristics and can interbreed to produce fertile offspring. The cactus plant, snake, and hawk belong to different species as they have distinct physical and genetic traits that prevent them from interbreeding.
