question 27

Multiple Choice

Marc Slattery conducted several experiments using both natural and simulated coral reefs.When reef species (sponges) were subjected to higher temperatures and lower pH,most likely the conditions that will exist in the future ocean environment,Slattery found that the reef species had slower growth rates and reduced reproduction.What was the cause of these results?

• A)The higher temperature directly affected the growth rate of the sponge.
• B)The higher temperature and lower pH reduced the sponges' symbiotic partners' ability to conduct photosynthesis.
• C)The lower pH prevented the sponge prodigy from attaching to a solid surface.
• D)The higher temperature and lower pH interfered with the sponges' reproductive cycle.
• E)The higher temperature and lower pH increased the sponges' symbiotic partners' ability to photosynthesize,and they were therefore able to survive on their own.
