Tidal Zones Flashcard

Front

What is the ecological importance of mollusks (particularly bivalves)?

Back

Mollusks, especially bivalves, are important as filter feeders, helping to maintain water quality by filtering out particles and nutrients.

Front

Identify the phylum that crustaceans belong to.

Back

Crustaceans belong to the phylum Arthropoda.

Front

Identify the type of symmetry starfish have.

Back

Starfish exhibit radial symmetry.

Front

What causes tides?

Back

Tides are caused by the gravitational pull of the moon.

Front

Why is adaptation for desiccation important for intertidal organisms?

Back

Adaptation for desiccation is crucial for intertidal organisms to prevent drying out when water is absent or low.

Front

What are the main zones of tidal areas?

Back

The main zones of tidal areas include the supratidal zone, intertidal zone, and subtidal zone.

Front

Define the intertidal zone.

Back

The intertidal zone is the area between the high tide and low tide marks, where organisms are exposed to air and water.

Front

What adaptations do organisms in the intertidal zone have for surviving harsh conditions?

Back

Organisms in the intertidal zone have adaptations such as tough outer shells, the ability to cling to surfaces, and mechanisms to retain moisture.

Front

What role do seaweeds play in tidal ecosystems?

Back

Seaweeds provide habitat, food, and oxygen for various marine organisms in tidal ecosystems.

Front

How do tides affect the feeding behavior of intertidal organisms?

Back

Tides influence feeding behavior by determining when organisms are submerged and can access food sources.
