• A. Oceans act as nature's carbon sink and abosrbs huge amount of carbon dioxide.
• B. The pH of ocean water has been increasing over the years.
• C. Certain marine species like algae and seaweed are likely to benefit due to high carbon dioxide levels.
• D. Marine calcifying species will suffer and their numbers will decrease due to ocean acidification.

Answer 1

Answer: (A), (C), (D)

Marine calcifying species will suffer and their numbers will decrease due to ocean acidification.

Ocean acidification is an emerging global pattern and an aspect of global climate change. It affects the marine food chains and the overall structure of marine ecosystems. It has an adverse impact since it calcifies species including oysters, clams, sea urchins, shallow water corals, deep sea corals, and calcareous plankton. With the pace of ocean acidification accelerating over the years, scientists, resource managers, and policymakers recognize the need for conserving oceans and marine resources.
