Question

1. one of effect of pythons in the everglades is *

a. they can grow to 20 feet long
b. they put endangered animals at greater risk
c. biologists can study them in their natural habitat
d. they control the alligator population

Explanation:

In the Everglades, pythons are invasive species. Their presence disrupts the ecosystem. Option a is about their physical growth, not an ecological effect. Option c is not a negative effect (assuming the context is about negative impacts of pythons). Option d is incorrect as pythons do not control the alligator population in a beneficial way. Endangered animals already face threats, and pythons (as predators) add to those threats by preying on them or competing for resources, which aligns with the concept of invasive species' negative ecological impacts.

Answer:

B. they put endangered animals at greater risk
