The basic needs of mammals - that is, what they need to survive - are water, food and protection. Of course, different mammals meet their needs in different ways, and the order of the need may be different at different stages in their lives,but essentially that's it! So where does the mammal get these things? The answer to that is from its habitat, i.e. the environment in which it lives naturally. If you think about chipmunks, for instance, they live in or near woodland where they are very well adapted to feed and to find shelter against harsh weather and predators. When they are very young, the chipmunks will depend on their mother for all their food (milk) and to protect them. She will do this by choosing a safe, sheltered place to give birth, by keeping the young warm with her own body-heat and by making milk to feed them. As they grow the young will become more independent until they have eventually learned to feed and take care of themselves in their habitat. Cougars, which may share the chipmunks' habitat, need water, food and protection, too, and one of the things that the young need to do is to learn to hunt chipmunks! This is one very good reason why it's important for us to take care to conserve habitats whenever we can. Finally, we are mammals,too, and so we share their basic needs.
