Scientific research shows that our global climate is changing. ocean temperatures and acidity are increasing, and the global sea level is rising. which of the following best predicts an outcome of this global climate change in a marine ecosystem? (2 points) select one: a. more species will be able to survive due to the less extreme temperatures in the ocean. b. the increased acidity will make it more difficult for harmful bacteria to survive. c. tectonic plate activity will increase and produce warmer ocean temperatures. d. many marine species will not be able to adjust quickly enough to survive.
