World Without Fish Chapter 6

What are some key components of marine ecosystems?

• Floating plants, plankton, fish, marine mammals, coral reefs, seaweed

• sand dunes

• seagulls

• whales

How does overfishing impact marine life?

• Overfishing reduces fish populations, disrupts marine ecosystems, and can lead to species extinction.

• Overfishing increases fish populations

• Overfishing has no impact on marine ecosystems

• Overfishing leads to more diverse marine species

Why is marine biodiversity important for the ecosystem?

• Marine biodiversity leads to ecosystem degradation

• Marine biodiversity contributes to ecosystem stability, resilience, and productivity, supporting various ecosystem services.

• Marine biodiversity has no impact on the ecosystem

• Marine biodiversity only benefits a few species in the ecosystem

What are some sustainable fishing practices that can help protect fish populations?

• Ignoring catch limits

• Implementing catch limits, using selective fishing gear, avoiding bycatch, protecting critical habitats, and promoting aquaculture.

• Destroying critical habitats

• Using dynamite for fishing

Describe the role of coral reefs in supporting marine biodiversity.

• Coral reefs contribute to the decline of marine species

• Coral reefs support marine biodiversity by providing habitats, shelter, food, and breeding grounds for a wide variety of marine species.

• Coral reefs are only important for human activities, not marine life

• Coral reefs have no impact on marine biodiversity

How can overfishing lead to the collapse of fish populations?

• Overfishing promotes the growth of fish populations.

• Overfishing has no impact on fish populations.

• Overfishing increases the fish population, leading to the collapse of fish populations.

• Overfishing reduces the fish population to unsustainable levels, disrupting the ecosystem and causing the collapse of fish populations.

Explain the concept of bycatch and its impact on marine ecosystems.

• Bycatch is the unintentional capture of non-target species during fishing operations, which can have significant negative impacts on marine ecosystems.

• Bycatch only affects land ecosystems

• Bycatch has no impact on marine ecosystems

• Bycatch is intentional capture of non-target species during fishing operations

What are some ways individuals can contribute to sustainable fishing practices?

• Supporting unsustainable seafood choices

• Using dynamite for fishing

• By following fishing regulations, practicing catch and release, supporting sustainable seafood choices, reducing plastic pollution, and participating in community clean-up efforts.

• Ignoring fishing regulations

Discuss the importance of protecting marine habitats for the overall health of the ocean.

• Protecting marine habitats only benefits a few species

• Marine habitats have no impact on the health of the ocean

• Protecting marine habitats is essential for the overall health of the ocean due to their role in maintaining biodiversity, supporting ecosystems, regulating climate, and providing resources for human use.

• The ocean can thrive without any marine habitats

How can implementing fishing quotas help prevent overfishing?

• By promoting the use of larger fishing vessels

• By setting limits on the amount of fish that can be caught, ensuring fish populations have the opportunity to replenish and sustain themselves.

• By allowing unlimited fishing to boost the economy

• By encouraging fishermen to catch as many fish as possible
