The map shows the global distribution of amphibians. The number of different amphibian species found in an area is shown by the various colors on the map. What likely explains the lack of species of amphibians in northern Africa and in Antarctica?

A) Amphibians require tropical rain forests in which to live, which are absent in Antarctica and northern Africa.
B) Amphibians require warm temperatures year-round, which prevents their colonization of northern Africa and Antarctica.
C) The life cycle of amphibians requires a migration to equatorial regions, which is geographically prevented in northern Africa and Antarctica.
D) Amphibians require water for reproduction and part of their life cycle. Deserts in Africa have little water and frozen ice in Antarctica reduces the water in which amphibians can lay eggs.

I chose C.

Answer 1

Incorrect, the correct answer is D. Amphibians require water for reproduction and part of their life cycle. Deserts in Africa have little water and frozen ice in Antarctica reduces the water in which amphibians can lay eggs.

Answer 2

The likely explanation for the lack of species of amphibians in northern Africa and Antarctica is D) Amphibians require water for reproduction and part of their life cycle. Deserts in Africa have little water, and frozen ice in Antarctica reduces the water in which amphibians can lay eggs. Unlike options A and B, which focus on the absence of specific environmental factors like tropical rainforests or warm temperatures, option D highlights the importance of water for amphibian reproduction. Option C, though it mentions migration, does not fully explain why amphibians are absent in these regions as it does not mention the lack of water availability.
