• Atoll

• Patch reef

The relationship between coral and their photosynthetic partners is...?

• Parasitic

• Mutualistic

• Competitive

• Commensalistic

The mutualistic relationship discussed exists between coral polyps and...?

When coral are not able to live within the right conditions, what happens?

• They move to a new habitat by drifting in the water

• They expel their symbiotic partner

• They form a larger polyp

• They adapt to the changing environment

An area with low turbidity will result in...?

• Slow growth of coral reefs

• Coral bleaching events

• Steady growth of coral

• Ocean acidification

When excess carbon from either greenhouse gas emissions or fossil fuel production enters the atmosphere, what is an outcome?

• Ocean acidification

• Coastline erosion

• Excess photosynthesis

• Increased enzyme function

Food webs are the root of all energy flow in diverse ecosystems, how do corals promote stability in food webs?

• Through primary productivity and nutrient supply

• Through eating organisms in trophic level 3

• Through maturation of photosynthetic algae

• Through serving as a habitat for energy to flow

How would heavy nutrient load factor into reef interactions?

• Loss of biodiversity by disrupting patterns

• Increasing biodiversity by providing nutrients

• Loss of biodiversity by ocean acidification

• Increasing biodiversity by promoting reef erosion

Which of the following is most likely to negatively impact a stable reef ecosystem?

• Construction of artificial reefs

• Addition a crown of thorns sea stars

• Reducing use of fossil fuels
