Coastal Ecosystems Flashcard

Front

What is a keystone species?

Back

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance. Its presence or absence can significantly impact the ecosystem.

Front

Which species is considered a keystone species in kelp forests?

Back

Otters are considered a keystone species in kelp forests because they keep sea urchin populations balanced, preventing overgrazing of kelp.

Front

What defines a coast?

Back

A coast is the general area where land and water meet, not a specific boundary.

Front

What is the role of mangroves in coastal ecosystems?

Back

Mangroves provide critical habitat for wildlife, protect shorelines from erosion, and help filter pollutants from water.

Front

How can mangrove forests be restored?

Back

Mangrove forests can be restored by growing mangroves from seeds and relocating them to areas where they have been removed.

Front

What are seagrass meadows?

Back

Seagrass meadows are underwater ecosystems formed by seagrass, which provides habitat and food for various marine species.

Front

Why are seagrass meadows important for marine life?

Back

Seagrass meadows serve as nurseries for young wildlife, offering protection from predators and a rich source of food.

Front

What is blue carbon?

Back

Blue carbon refers to carbon captured by oceanic and coastal ecosystems, such as mangroves, seagrasses, and salt marshes.

Front

What is the difference between kelp forests and mangrove forests?

Back

Kelp forests are underwater ecosystems dominated by kelp, while mangrove forests are coastal ecosystems characterized by salt-tolerant trees.

Front

What environmental conditions do kelp forests require?

Back

Kelp forests require low energy environments with cold, nutrient-rich waters.
