Ocean acidification is of considerable concern to environmental scientists as it could impact ocean biodiversity significantly
one of the impacts is the weakening of calcium carbonate shells in invertebrates, which releases carbon into the ocean. what
describes the relationship between ocean acidification's causes and effects?
(a)increased carbon dioxide levels in the atmosphere cause a decrease in
ocean ph. the dissolution of calcium carbonate shells increases carbon in
the ocean. this is a positive feedback loop, where the ocean's ph will
continue to drop
(b)decreased carbon dioxide levels in the atmosphere cause a decrease in
ocean ph. the dissolution of calcium carbonate shells increases carbon in
the ocean. this is a negative feedback loop, where the ocean's ph will
retum to homeostasis
(c)increased carbon dioxide levels in the atmosphere cause an increase in
ocean ph. the dissolution of calcium carbonate shells increases carbon in
the ocean. this is a positive feedback loop, where the ocean's ph will
continue to increase
(d)decreased carbon dioxide levels in the atmosphere cause a increase in
ocean ph the dissolution of calcium carbonate shells increases carbon in
the ocean. this is a negative feedback loop, where the ocean's ph will
