Which of the following is true regarding possible impacts on ecosystems that might occur as a result of climate change?
A) Studies have demonstrated there will be no impact on plant distributions.

C) The transition between prairie grasslands and northern forests is expected to move northward with increasing temperatures.
D) Beech trees in eastern North America will not change in distribution.

Question

Quizplus · Accepted Answer

Climate change is expected to cause shifts in the geographic range and distribution of plant and animal species. As temperatures increase, the transition zone between prairie grasslands and northern forests is predicted to move northward, with prairies potentially shrinking and forests expanding. Studies have also found that some plant species are shifting their distributions in response to climate change. Therefore, option C is the correct choice. Options A, B, and D are incorrect because studies have demonstrated changes in plant distributions, the transition zone is shifting, and some tree species are also predicted to experience changes in distribution.
