Q. Which of the following statements describes the impact of climate change on the balance of an ecosystem in a better manner?Select the correct answer using the code given below.

[A] Agricultural expansion eliminating forest and forcing animals that lived there to move into new areas.

[B] Certain alignments of the sun and the moon result in extra-large tidal ranges that expose some aquatic animals to air.

[C] Consistent, milder-than-average winters allowing more insect eggs to survive which is increasing the frequency of severe insect infestations of trees.

[D] All of the above

Answer: C
Notes:

Statement a is wrong, this example describes the effects of land-use change on woodland and meadow habitats. The example does not describe the effects of climate change, which impacts the balance of an ecosystem by shifting typical weather patterns.

Statement b is also wrong. This example describes a regularly occurring pattern in nature, so the affected ecosystems are likely adapted to these fluctuations.

Climate change involves long-term changes to weather patterns that can disrupt the balance of existing ecosystems. Statement c does illustrate an effect of climate change, describing a long-term change in winter weather that is affecting insect and tree populations.
