Question

Ecological, species, and genetical reasons contribute to the differences between rainforests and Arctic tundra for organisms. Which of the following statements is true regarding these differences?

a. Rainforests and Arctic tundra have similar ecological characteristics due to their extreme climates.
b. The species diversity is higher in the Arctic tundra than in rainforests due to adaptation to cold conditions.
c. Genetical differences play a minor role in the adaptation of organisms to their respective environments.
d. Differences in temperature, precipitation, and vegetation contribute to distinct ecological, species, and genetical characteristics between rainforests and Arctic tundra.

Answer 1

As there are biological, species, and genetic reasons why organisms in rainforests or Arctic tundra differ from each other. The correct statement is that differences in temperature, precipitation, and vegetation contribute to distinct ecological, species, and genetical characteristics between rainforests and Arctic tundra. The correct option is d.

Step-by-step explanation:

The differences between rainforests and Arctic tundra are quite significant and can be attributed to various ecological, species, and genetical aspects. The statement that is true regarding these differences is: d. Differences in temperature, precipitation, and vegetation contribute to distinct ecological, species, and genetical characteristics between rainforests and Arctic tundra.

As one moves towards the poles from the equator, there is a noticeable increase in biodiversity, which is evidently lower in the Arctic tundra compared to the rainforests. Hence, d is the correct option.
