Explain why changes in climate can result in the extinction of a species.

The changes in environment can cause the raising of the sea level, which can push animals further inward, which in turn destroy habit, as they began to get clumped together vegetation begins to go away, thus resulting in less species, also hotter climate makes sure that animals with very heavy coats of fur, die out pretty quickly if not cooled (over heating)

Changes in climate (too hot or too cold) can affect multiple spiecies of animals due to disappearance of their habitats or/and food.

Every living animal and plant is part of the food chain. If the food chain is broken, many species would be in danger of extinction.
