Looking further…<br />The key deer rely on having freshwater to live on. Some of the islands do not have freshwater sources. <br />The deer are herbivores. <br />What is an herbivore?<br />
What are Adaptations? <br />Natural Selection – <br /> survival of the fittest<br /> organisms that are best able to survive in an environment survive<br />Why is this important in a dynamic ecosystem?<br />What would have happened if the Key Deer were as large as a deer you would see in your backyard?<br />
