Carbon dioxide diffuses into the ocean carbon cycle via the air-sea surface exchange. molecules of co2 enter the ocean by diffusing into the surface waters and dissolving. the amount of co2 that diffuses and dissolves in the surface water depends on several variables. scientists have noted that more co2 diffuses and dissolves in colder sea surface water and less co2 diffuses and dissolves in warmer water. let's assume the predictions of scientists predicting a warming climate are true. can you predict the changes to this model if average ocean temperatures increase as well?
a) warmer oceans would result in an increase in dissolved co2. that in turn would result in a shift in the oceans to more photosynthesis, respiration, and decomposition.
b) warmer oceans would result in an increase in dissolved gases in the oceans. an increase in the co2 would result in an increase in the rate of photosynthesis of autotrophs found in the oceans.

c) warmer oceans would mean less dissolved co2 as well as other gases such as oxygen in the global ocean. lower co2 would result in a decrease in photosynthesis of autotrophs living in the oceans.
d) warmer oceans result in less dissolved co2 in the oceans and more co2 diffusing into the atmosphere. the extra co2 would cause increased global warming, eventually causing a spike in earth's temperatures and massive extinctions.
