The Rocky Shore

Vertical zonation on rocky shores is mostly the result of differences in tolerance to:

• Wave action

• Exposure.

• Predation.

• Light.

Competition for which resource is a dominant factor in the rocky intertidal zone?

• food

• light

• oxygen

• space

Which is considered a keystone predator in the middle intertidal zone?

• birds

• crabs

• limpets

• sea stars

The lower limit of the intertidal zone is the:

• Average high tide.

• Average middle tide.

• Lowest low tide.

• Lowest edge of the rocky substrate.

Besides fluctuations in salinity and water levels, intertidal organisms must also withstand wide variations in:

• Temperature.

• Light level.

• Sediment deposition.

• Current velocity.
