Migration By: Cindy Ocampo
What is migration?
Migration is where a group of species travels long distances during seasons. Some species that migrate are birds, mammals, and insects. The reason thats certain species migrate is the changes in climate. Another reason is that they go to find food sources that are no longer around where they live. Also certain species travel long distances to help reproduce.
Animals like bears go into a deep sleep, this is a state of inactivity. Their breathing slows down, the animal doesn't eat or use the bathroom. Hibernation happens during cold seasons. Hibernation helps them survive since the foods that animals are not around during the cold winters. A deep sleep will help them pass through the cold climates without the need to look for survival
