ESS

All of the following are true about Zooxanthellae EXCEPT:

They provide protection to the corals because they are toxic for animals to eat

Which of the following statements concerning ocean acidification are TRUE? (Choose all that apply)

-As pH decreases, saturation state also decreases -As saturation state decreases, the ability of organisms to calcify decreases =As CO2 increases, pH decreases - As CO2 increases, saturation state decreases

How is the life-cycle of fish impacted by human fishing pressures? (Choose all that apply)

-Organisms tend to be smaller when they've reached maturity -Organisms tend to produce fewer viable eggs -Organisms reach maturity faster

Zooxanthellae are: (choose all that apply)

-phytoplankton -Phototrophic autotrophs

A good reproductive adaptation for a successful K-strategist would be:

A seal mother producing an extra fatty source of milk for a single pup so they become large and independent sooner

What impact will ocean acidification have on the lysocline?

Ocean acidification will cause the lysocline to shoal (get shallower)

How does extensive exploitation over long time periods exploit the physical size of fish?

Remaining fish tend to get smaller

Site A has an alpha biodiversity value of 10. Site B has an alpha biodiversity value of 13. Together, they have a gamma biodiversity value of 19. What can be said about sites A and B?

Sites A and B have 6 species that are the same

Theoretical predictions suggest that the North Pole should be cooler than it actually is. What helps to warm regions at high latitudes?

Warm air from the equator moves toward the poles before descending

Why do some organisms need saturation states much greater than 1 to calcify?

When saturation states are high, carbonate concentrations are high

All of the following would be considered ecosystem services EXCEPT

all of the above

Corals reefs are considered the "oases" of the oceans. Corals live in:

none of the above

When carbon dioxide (CO2) is added to seawater (H20), which of the following happens? (check all that apply)

the carbonate ion concentrations (CO32-) in the surface oceans decreases -the bicarbonate (HCO3-)ion concentration in the surface oceans increases -the hydrogen ion concentration in the surface oceans increases
