Front

What is the approximate ratio of CO2 dissolved in the ocean compared to the atmosphere?

Back

60 times as much CO2 is dissolved in the ocean as in the atmosphere.

Front

Which process removes carbon dioxide from the atmosphere?

Back

Photosynthesis.

Front

What is phosphorus needed for in organisms?

Back

Phosphorus is needed for the production of ATP, cell membranes, and DNA, but not for chloroplasts.

Front

What happens to temperature as you descend through the water column?

Back

Temperature decreases.

Front

What is a halocline?

Back

The zone of the ocean in which salinity increases rapidly with depth.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of ATP in living organisms?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells.

Front

Explain the significance of carbon dioxide in the ocean.

Back

Carbon dioxide is crucial for marine life as it is used in photosynthesis by phytoplankton and affects ocean chemistry.

Front

What is the relationship between pressure and depth in the ocean?

Back

Pressure increases as you descend deeper into the ocean.

Front

What is the importance of chloroplasts in plant cells?

Back

Chloroplasts are the organelles where photosynthesis occurs, converting light energy into chemical energy.
