A)The decreasing temperature of the ocean water will increase the survivorship of fish larvae.
B) There will be a greater percentage of fish larvae that survive than mature fish that survive.
C) The increasing carbon dioxide concentrations will increase the density of adult fish skeletons.
D) The decreasing pH of the ocean water will decrease the survivorship of fish.
