Question

For which of the following reasons do small isolated islands have a greater rate of species extinction than larger, less isolated islands?

Responses

Small isolated islands are more likely to receive more migrating species.


Small isolated islands provide opportunities for a greater diversity of species.


Because of their size, small isolated islands accumulate more species by chance.

Small isolated islands have a lower availability of resources.

Because they have fewer available niches, small isolated islands are targeted and colonized by species.

Answer 1

Small isolated islands have a lower availability of resources.

Step-by-step explanation:

Small isolated islands have a greater rate of species extinction than larger, less isolated islands because they have a lower availability of resources. Small islands often have limited resources such as food, water, and space, which can lead to competition between species for these resources. In addition, small populations on small islands are more vulnerable to random events like disease outbreaks or severe weather, which can lead to rapid declines in population sizes and a higher risk of extinction. Therefore, the limited availability of resources on small isolated islands can contribute to a higher rate of species extinction compared to larger, less isolated islands
