How did Noah's Arc accommodate for such a diverse collection of species?

Actually polar bears can survive quite well away from cold weather. Lions were still vegetarians. Fish and whales can survive in water so they weren't on the ark at all. I'm sure God put all the animals in a state of hibernation. Dinosaurs were on the ark but like i said they were all vegetarian. The animals were also penned seperately you know the pair of lions they had their own pen.
