Which of the following can be regarded as the negative effect of climate change on the ecosystem Consistent, lower-than-average winter snowfall in a mountain ecosystem causing a decrease in water supply to rivers later in the year, impacting the survival of some populations. Trawling in a marine ecosystem removes large quantities of fish and destroys corals, decreasing the amount of available food and habitat resources. Select the correct answer using the given code below

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: A

Notes:

Trawling disrupts an ecosystem through overexploitation of resources and habitat loss. So, this example does not describe the effects of climate change, which disrupts an ecosystem by shifting typical weather patterns.
Climate change involves long-term changes to weather patterns that can disrupt the balance of existing ecosystems. So, statement 1 does illustrate an effect of climate change, describing a consistent change in winter weather that is affecting the survival of populations.
