Why Do Temperate Oceans Tend To Be More Productive Than Tropical Oceans?

Why Do Temperate Oceans Tend To Be More Productive Than Tropical Oceans?

The answer is that tropical oceans are more productive than the temperate oceans. There are storms in the tropics that allow mixing of water and food.

Why is productivity low in tropical regions quizlet?

Tropical regions have low biological productivity due to the strong thermocline. There is a lack of sunlight in polar regions.

Which conditions in the ocean promote high productivity?

The water that rises to the surface is usually cold and rich in vitamins and minerals. The surface waters often have high biological productivity because they are fertilized.

Why is the open ocean so low in productivity?

There is a lot of sun in surface waters, but not a lot of nutrition. The ocean surface isn’t very productive. There isn’t any upwelling in the water because it is too deep.

Which ecosystem has the greatest average primary productivity?

The highest net primary productivity can be found in swamps and marshes, while the lowest can be found in deserts.

Why is productivity low in tropical regions group of answer choices?

Productivity is limited in the tropics due to lack of sunlight. The fall bloom is limited in the middle-latitude oceans because they don’t have enough food. Productivity is limited in the tropics because of the lack of vitamins and minerals.

Why do most areas of tropical regions have low primary productivity?

The lack of sunlight causes productivity to be limited in the tropics. The lack of sunlight causes the spring bloom to be limited. Productivity is limited in tropical oceans because they don’t have enough food. The lack of sunlight limits the fall bloom in the ocean.

Why are tropical waters highly unproductive?

The waters of the tropics are very productive. Plants are able to grow large enough to grow organically. The organic material is the building block of the food chain.

Why are cold oceans more productive?

Cold waters tend to have more nutrition than warm waters, which is why phytoplankton are more plentiful in cold waters.

Which part of the ocean is most productive?

The eastern parts of the Pacific and Atlantic Ocean are home to some of the most productive marine areas in the world. 20 percent of the world’s fish harvest is provided by them, and they support a large diversity.

Why do polar waters have a lower productivity than temperate waters?

The polar oceans have high primary productivity. The polar oceans have high productivity due to the lack of thermocline. In the winter, the polar oceans are very productive.

How does water temperature relate to productivity?

The warmer the surface waters get, the less mixing there is between them and the deeper water. Productivity goes down as the surface becomes less fertile for phytoplankton to grow.

What are the most productive ecosystems?

Productivities of 10 to 25 x 103 kcal/m2/yr can be achieved by fertile estuaries and marshes, coral reefs,terrestrial vegetation on moist alluvial deposits, and intensive agriculture.

Why do the tropical oceans have a steady low rate of productivity year round?

There is a constant low level of productivity in the tropics due to a permanent thermocline.

Which type of aquatic ecosystem has the highest net primary productivity?

The highest net primary productivity can be found in coral reefs. It has a high rate of photosynthesis because of the high light intensity.

Where is the ocean least productive?

Deep oceans have the lowest availability of solar radiation. The oceans are not as productive as they could be.

Is the Southern Ocean productive?

High levels of primary productivity can be found in the Southern Ocean andAntarctica. Despite the lack of iron in the water, these plants are able to adapt and survive.

Why do coastal regions tend to have more primary productivity?

How does coastal upwelling affect biological productivity? It brings water to the surface that is rich in vitamins and minerals.

What water is most productive?

The large coastal upwelling areas on the eastern edges of the Pacific and the Atlantic are some of the most biologically productive marine areas in the world.

What is primary productivity in the ocean?

The primary productivity is the rate at which carbon dioxide is converted into organic material. The producers form the base of the entire food web on land and in the ocean.

How does water temperature affect the size and distribution of phytoplankton blooms?

The increase in water temperature increases the amount of plankton in the water. With each 10C increase in temperature, the growth rates of the phytoplankton are almost doubled.

How can primary productivity be improved?

It is possible to get a high primary productivity rate when the physical factors are good. The primary productivity rate can be increased by the presence of some forms of secondary energy.

What is the optimal temperature for phytoplankton?

The unimodal size scaling pattern of growth, with a peak at intermediate cell sizes, is observed at 18 C, 25 C and at the optimal temperature for growth, and that it prevails regardless of the standing stock metric used.

Which ecosystems are most productive and why?

Primary productivity refers to the amount of energy that can be accumulated. Coral reefs are the most productive in aquatic environments. In the tropics, the highest productivity can be found.

Why are tropical wet forests and estuaries most productive?

There is plenty of solar light and water in the tropics. A typical estuary has high primary productivity because it is shallow, has a lot of sunlight, and is rich in minerals from the sea bed.

Which two marine ecosystems are most productive?

Brown algal beds, seagrass beds and coral reefs are some of the most productive systems in the ocean.

Which of the following contributes the maximum to the net primary productivity?

There is a new date for the 11th. Which of the following is associated with the highest rate of productivity? The highest rate of productivity can be found in the grassland.
