Which of the following statements is consistent with the information provided in the graph? Choose 1 answer: The extinction rate between the end-Permian and the end-Triassic extinctions indicates this was a time of global ecological stress. The tetrapod families that were lost during the end-Permian extinction returned after a lag of a few million years as they re-populated previously occupied habitats. Since the end-Permian extinction, the number of tetrapod families on Earth has halved roughly every 100 million years. Tetrapods underwent an adaptive radiation after the end-Cretaceous extinction, likely due to the use of ecological niches made available by the extinction event.

Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.
