Areas of the open ocean are often very deep. Primary productivity relies on sunlight, and sunlight only penetrates the first 10m or so (varies widely) of the ocean surface. Therefore, only this surface zone is photosynetically productive, which in turn fuels secondary (small crustaceans, zooplankton, etc.) and tertiary (fish) production.

What limits primary productivity in tropical oceans?
Primary productivity in tropical oceans is primarily limited by nutrient availability, particularly nitrogen and phosphorus. Factors such as temperature, light availability, and water movement can also influence primary productivity in tropical oceans. Upwelling events that bring nutrient-rich waters to the surface can enhance primary productivity in these regions.
How much water covers the oceans surface?
The oceans surface is 100% water.
What limits primary productivity in tropical oceans Why?
Primary productivity in tropical oceans is limited by factors such as nutrient availability, light availability, and temperature. Nutrient availability may be limited due to low input from upwelling currents or lack of mixing in some areas. Light availability may be restricted due to cloud cover, depth of the water column, or turbidity. Temperature can also limit primary productivity as it affects the metabolic rates of marine organisms.
What is the effect of wind pushing on the surface water of the oceans?
oceans are the best.
Where is most of the water found on the earth?

What planet has liqiud water oceans?

Does lakes contain surface water?
Yes, it does . Actually, surface water- Is the water in rivers, lakes, oceans and so on.
Water from oceans and earths surface that changes to water vapor?

Where is most of Earth's surface water found?
