26. As you study two closely related predatory insect species, the two-spot and the three-spot avenger beetles, you notice that
each species seeks prey at dawn in areas without the other species. However, where their ranges overlap, the two-spot avenger beetle hunts at night and the three-spot hunts in the morning. When you bring them into the laboratory and isolate the two different species, you discover that the offspring of both species are nocturnal. You have discovered an example of A) mutualism. B) Batesian mimicry. C) commensalism. D) resource partitioning.
Resource partitioning explains how species that are similar (in this case the two-spot and the three-spot avenger beetles) use their resources together (coexist). They live in the same community and use the same resources, but they don't push one another to extinction through competition. They use the same limiting resource at different time and thus, compete less with one another.
I believe the answer is C. because when the dinosaurs thrived they ate most of the mammals which were small animals but when the dinosaurs went extinct the mammals grew larger in size and started to thrive.
