Adaptations are skills which help an animal or plant to survive in their environment. They develop over time. Adaptations can be physical or behavioral.

Physical adaptations are changes to a plant or an animal’s appearance over time. Desert tortoises have a hard shells around its body to protect itself. This is an example of a physical adaptation.

A behavioral adaptation is a change to animals’ daily actions. Some desert animals are nocturnal animals, which means they are active at night and sleep during the day. The California leaf-nosed bat prefer the night time because it is cooler. They want to avoid the daytime desert heat. This is a behavioral adaption.

Some desert plants survive in their environment by storing water inside themselves. Living things need water to survive. You have water inside your body, and Joshua trees have water inside their trunks. Joshua trees protect that water by having bark. By folding their old leaves down over their trunks they keep shaded so they stay cool.

Sleep is not one state but a cycle through several, each doing different work. Most sleep disorders are a failure to complete that cycle rather than a shortage of hours.
