Review the graph showing marine fishing rates.If the fishing rate in Asia continues to grow, what will most likely happen as a result?

The diagram shows a boat using sonar to gather information in the ocean. What is most likely being measured with this technology?

• ocean depth
• ocean temperature
• pH level
• turbidity level
  

The population of photosynthetic organisms is higher in the neritic zone and surface waters than in the deep ocean. Which statement best explains the reason for this?

• There is more space for plants to grow in these areas of the ocean.
• There is more dissolved oxygen for plants in these areas of the ocean.
• The availability of sunlight and nutrients supports photosynthetic organisms.
• The high salinity and cool temperature supports photosynthetic organisms.
