Climate changes can produce various effects in ecosystems. which of the following is a way that marine ecosystems can be affected by climate warming trends?
a.
decreased ocean acidity
b.
increased populations of fish
c.
decreased levels of carbonate
d.
all of the above

When there is a presence of climate change, the marine ecosystem will be affected in many different ways, and the answer to that is the decreased levels of carbonate. It is because when there is a climate change, ocean acidity will increase as they take up carbon dioxide, making carbonate decrease. When there is climate change, fishes migrate, so there is no possibility that there will be an increase population of the fish. So the correct answer is letter C.
