Question

Harvey is studying the turtles that live in a pond.His knowledge of ecology will be most useful for explaining which of these observations of the turtles?

Answer 1

His knowledge on ecology will be helpful in determining how the turtles interact with the environment. Ecology is the study of ecosystems, and turtles play an important role as a consumer.

Answer 2

My best logical guess is D. Why would the turtle have to go above the water. If their living in a pond, then studying them above water makes no sense. So it's most useful if they are remaining underwater for many minutes at a time then reach for the surface, so that's the answer most likely, but i have no idea.

So... D. A turtle may remain underwater for several minutes, but then surfaces for at least a brief moment.
