## Step 1<br />The first question asks for three reasons why islands have higher extinction rates than the mainland. The reasons are:<br />- Smaller population sizes: Islands often have smaller populations than the mainland, which makes them more vulnerable to extinction.<br />- Limited resources: Islands often have fewer resources than the mainland, which can lead to higher extinction rates.<br />- Isolation: Islands are often isolated from the mainland, which can make it harder for species to survive.<br /><br />## Step 2<br />The second question asks how species colonize islands. Species colonize islands through a process called dispersal, where they travel from the mainland or other areas to the island.<br /><br />## Step 3<br />The third question asks for two factors that increase the colonization rate and explains how they work. The two factors are:<br />- Proximity to the mainland: The closer an island is to the mainland, the more likely species are to colonize it.<br />- Suitable habitats: The more suitable the island is for a species, the more likely it is to be colonized.<br /><br />## Step 4<br />The fourth question asks for two factors that influence the extinction rate of species on the island and explains each. The two factors are:<br />- Population size: Smaller populations are more vulnerable to extinction.<br />- Environmental changes: Changes in the environment, such as climate change or natural disasters, can increase the extinction rate.
