Human Dependence on Oceans

What is the process of photosynthesis?

• Photosynthesis is the process by which plants convert sunlight into energy, producing oxygen as a byproduct.

• Photosynthesis is the process by which animals convert food into energy, releasing carbon dioxide.

• Photosynthesis is the process of breaking down glucose to release energy in the absence of oxygen.

• Photosynthesis is the process by which fungi absorb nutrients from their environment.

What role do oceans play in regulating the Earth's climate?

• Oceans absorb carbon dioxide and heat, helping to regulate the Earth's climate.

• Oceans primarily serve as a habitat for marine life.

• Oceans have no significant impact on the Earth's climate.

• Oceans are responsible for creating weather patterns on land.

What is ocean pollution?

• The introduction of harmful substances into the ocean, affecting marine life and ecosystems.

• The process of cleaning the ocean to remove waste and debris.

• The natural occurrence of ocean currents and tides.

• The increase in ocean temperature due to climate change.

What is the significance of coral reefs in oceans?

• Coral reefs provide habitat for diverse marine species and protect coastlines from erosion.

• Coral reefs are primarily used for fishing and harvesting seafood.

• Coral reefs are important for oil drilling and extraction.

• Coral reefs serve as a barrier for large ships to navigate safely.

Which of the following is NOT a source of pollution in the ocean: Fertilizers, Sand drifting, Oils, or Emissions?

• Fertilizers

• Sand drifting

• Oils

• Emissions

How do oceans affect weather patterns?

• Oceans influence weather patterns by storing and distributing heat and moisture in the atmosphere.

• Oceans have no effect on weather patterns whatsoever.

• Oceans only affect weather patterns during the summer months.

• Oceans primarily cool the atmosphere, leading to less rainfall.

What are the effects of oil spills on marine life?

• Oil spills can cause suffocation, poisoning, and habitat destruction for marine animals.

• Oil spills have no significant impact on marine life.

• Oil spills only affect the surface of the water and not the organisms below.

• Oil spills can enhance the growth of certain marine species.

What is phytoplankton?

• Tiny, microscopic plants found in oceans that perform photosynthesis and produce oxygen.

• Large marine animals that feed on smaller fish.

• Bacteria that live in freshwater and consume organic matter.

• Coral reefs that provide habitat for marine life.

What are some common sources of ocean pollution?

• Fertilizers used on land

• Plastic waste from households

• Industrial waste from factories

• Sewage from treatment plants

What process do phytoplankton use to produce oxygen?

• Respiration

• Photosynthesis

• Fermentation
