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