Rocky and Sandy Shores Gladd

This area of the ocean only makes up 10% of the total ecosystem size, but has 90% of its biodiversity.

• The coastal/tidal zones

• The photic zone in the open ocean

• The aphotic zone in the open ocean

• The benthic zone

The Lugworm is found on sandy shores. Which adaptation best allows this worm to survive in this habitat?

• Attaching to a hard substrate

• Clamming up

• can withstand dessication

• Burrowing into the sand

Which factor contributes to the high biodiversity found in the intertidal zone of rocky shores?

• Uniform environmental conditions

• Limited space for organisms to inhabit

• A wide range of microhabitats and ecological niches

• The absence of predators

Why are organisms in the upper intertidal zone typically more tolerant of environmental extremes than those in the lower zones?

• They have access to more food sources.

• They are smaller in size, which makes them more adaptable.

• They have evolved adaptations to withstand longer periods of exposure to air and sunlight.

• They are closer to freshwater sources.

What role do tide pools play in the intertidal zone of rocky shores?

• They provide a habitat for deep-sea organisms.

• They serve as temporary refuges for organisms to avoid desiccation.

• They are primarily used by birds for drinking water.

• They increase the salinity levels of the surrounding area.
