What is one possible outcome of increased levels of carbon dioxide in the troposphere?
A) The rate of photosynthesis may decrease because there are no other limiting factors.
B) More northern species may start to migrate southward.
C) Species diversity in tropical rain forests, such as the Amazon, may be altered.
D) The number of plant-eating insects in rain forests may decrease.

Quizplus · Accepted Answer

Increased levels of carbon dioxide in the troposphere can lead to changes in temperature and precipitation patterns that can have significant impacts on species diversity in tropical rain forests, such as the Amazon.

Answer: A
 Increased levels of carbon dioxide can lead to a decrease in the rate of photosynthesis because there are no other limiting factors present.

Answer: B
 While increased levels of carbon dioxide may have some impacts on species distribution, it is not the most significant outcome of such an increase.

Answer: D
 There is no clear evidence to support the claim that increased levels of carbon dioxide would lead to a decrease in the number of plant-eating insects in rain forests.
