Question

which of these is a way climate change positively affects organisms?
a. reduces current food supply
b. provides new habitats
c. increases ocean acidity
d. reduces habitat area

Explanation:

• Option A: Reducing the current food supply is a negative impact of climate change on organisms as it can lead to starvation and population decline.
• Option B: Providing new habitats can be a positive effect. For example, as temperatures change, some regions that were previously too cold or inhospitable for certain species may become suitable, allowing for new colonization and potentially increased biodiversity in those new areas.
• Option C: Increasing ocean acidity is harmful. It can damage the shells of marine organisms like mollusks and corals (coral bleaching), disrupt the food chain in marine ecosystems, and negatively impact many aquatic species.
• Option D: Reducing habitat area (e.g., due to rising sea levels flooding coastal habitats or desertification reducing arable land) is a negative consequence as it limits the space available for organisms to live, breed, and find resources.

Answer:

B. Provides new habitats
