Marine Ecosystems and Conservation Concepts

The video celebrates Earth Day by exploring the unique ecosystems of Southern California, focusing on kelp forests and the rocky intertidal zone. It highlights the conservation efforts for the giant sea bass and the impact of sea star wasting syndrome. The video concludes with tips on protecting these ecosystems by reducing urban runoff and being mindful of human impact.

What is the primary focus of the special livestream introduced by Evelyn?

• Unique ecosystems, particularly kelp forests

• The role of technology in conservation

• The history of Earth Day

• The science of climate change

Where are giant kelp forests primarily found?

• Along the Atlantic coast

• In the Arctic Ocean

• Along the Pacific coast of California

• In the Indian Ocean

What makes the giant sea bass unique among fish found off the California coast?

• They are the most colorful fish

• They are the largest bony fish

• They are the fastest swimmers

• They have the longest lifespan

What was a major threat to the giant sea bass population in the early 20th century?

• Climate change

• Overfishing

• Pollution

• Habitat destruction

What is the intertidal zone?

• A freshwater ecosystem

• The deepest part of the ocean

• The area between high tide and low tide

• A desert ecosystem

What role do sea stars play in the intertidal ecosystem?

• They are primary producers

• They are predators

• They are decomposers

• They are scavengers

What was the impact of the sea star wasting syndrome?

• Sea stars falling apart

• Increased sea star population

• Decreased mussel population

• Increased coral reef growth

What is one way individuals can help protect the intertidal ecosystem?

• By collecting sea stars

• By treading lightly when visiting

• By feeding the fish

• By planting more trees

How can urban runoff affect marine ecosystems?

• It has no effect

• It can pollute the ocean

• It helps clean the ocean

• It provides nutrients for fish

What is a suggested action to reduce urban runoff?

• Using storm drains for waste

• Limiting water runoff into streets

• Throwing trash on the ground

• Watering lawns excessively
