We take most adaptations for granted because they are so familiar. For example, a season with hot summers and cold winters will mainly have deciduous trees, the trees shedding their leaves before winter starts. If we live in a place like this, we just take these seasonal adaptations as normal. But they are not. They will not occur in other parts of the world. In spring, bulbs, which are another adaptation, will begin to shoot, triggered by a rise in soil temperature. Then most of these bulb plants (which are often forest plants) can grow, produce leaves, flower and set seed all while they still have direct sunlight, because the trees only get their leaves back again in late spring.

When you look around you at the homes of animals and plants across the world, you find that each living thing occurs most commonly where it is best adapted to survive.

This is a video of a roadrunner bird in a desert. It doesn't need to drink at all, but gets its moisture from the blood (which is nearly all water) in the food it eats. Its food, such as lizards, can get moisture from dew over night, and from the animals and plants they eat. The plants, on which all of this depends, hold on to the moisture they get in occasional rainstorms by storing it in their big stems.
