Adaptations

Introduction

All living things must adapt in order to survive in their environment, the species that is better adapted will be able to live longer in this environment, have more offspring and pass on their genotype as much as possible. See evolution.

We are going to look at an example from the plant and animals kingdoms that demonstrate adaptations that have evolved to cope in extreme environments.

The Cactus

Firstly we shall look at how a plant is adapted to a very warm climate.

These are just some of the many adaptations it has to help it to survive:

The Polar Bear (Ursus maritimus)

Now we shall have a look at have an animal is adapted to living in a cold environment.
