Fossil fuels are commonly used as an energy source for transportation vehicles. burning fossil fuels has led to more carbon dioxide in the atmosphere and dissolved in seawater. which of the following describes how burning fossil fuels is most likely to impact marine organisms? a. increased levels of carbon dioxide in seawater would increase the rate of photosynthesis in marine plants. b. dissolved carbon dioxide in seawater would cause an increase in shellfish populations due to strengthened skeletons. c. increased levels of carbon dioxide in seawater would cause ocean acidification and weaken corals. d. dissolved carbon dioxide in seawater would cause invasive species to out-compete native species.
