Ocean Exploration

What are the different marine ecosystems?

• Coral reefs, kelp forests, open ocean, estuaries, deep sea

• Mangrove swamps

• Grasslands

• Tundra

How do coral reefs contribute to marine biodiversity?

• Coral reefs contribute to marine biodiversity by providing habitats for a wide range of marine species.

• Coral reefs contribute to marine biodiversity by creating pollution in the marine environment.

• Coral reefs contribute to marine biodiversity by causing harm to marine species.

• Coral reefs contribute to marine biodiversity by reducing the number of marine species.

Explain the concept of ocean acidification and its impact on marine life.

• Decreased pH levels in seawater have no impact on marine organisms

• Ocean acidification is caused by excessive fishing practices

• Marine life benefits from ocean acidification

• Ocean acidification is the process of carbon dioxide dissolving in seawater, leading to a decrease in pH levels. This can harm marine life, particularly those that depend on calcium carbonate for shell and skeleton formation.

What are the major threats to marine ecosystems?

• Oil spills, nuclear waste, deforestation

• Acid rain, deforestation, overpopulation

• Pollution, overfishing, habitat destruction, climate change, and invasive species

• Global warming, deforestation, air pollution

How does climate change affect ocean temperatures?

• Climate change leads to ocean temperatures remaining constant

• Ocean temperatures decrease as a result of climate change

• Climate change has no impact on ocean temperatures

• Climate change causes ocean temperatures to rise due to increased greenhouse gases trapping heat in the atmosphere.

Discuss the role of phytoplankton in the marine food chain.

• Phytoplankton are only consumed by top predators in the marine food chain

• Phytoplankton are predators in the marine food chain

• Phytoplankton play a crucial role as primary producers at the base of the marine food chain, providing energy for higher trophic levels.

• Phytoplankton have no impact on the marine food chain

What are some strategies to mitigate the effects of climate change on oceans?

• Destroying marine habitats

• Reducing carbon emissions, protecting marine habitats, implementing sustainable fishing practices, reducing plastic pollution, and promoting ocean conservation efforts.

• Increasing carbon emissions

• Implementing unsustainable fishing practices

Describe the importance of mangrove forests in coastal ecosystems.

• Mangrove forests contribute to increased pollution in coastal areas

• Mangrove forests are important in coastal ecosystems for providing protection against erosion, storm surges, and tsunamis, acting as nurseries for marine species, maintaining water quality, and storing carbon.

• Mangrove forests are only important for aesthetic purposes in coastal regions

• Mangrove forests have no impact on coastal ecosystems
