Which factors determine productivity in temperate oceans?

Ocean Productivity. Abiotic factors like solar radiation and nutrients, and biotic factors like zooplankton predation may affect ocean primary productivity. Productivity varies with the season, and also locally and globally.

What limits or controls ocean productivity in temperate oceans?

Terms in this set (15)

Productivity is low and limited because of lack of nutrients. The sun is more directly over head > light penetrates deeper into tropical ocean than in temperate and polar waters. Develop from friction btw the ocean and the wind.

What limits productivity in polar oceans?

Reduction of sunlight by sea ice can be a major limiting factor for primary productivity in the Arctic Ocean.

In what type of oceans would productivity be highest?

Although they occupy just fewer than two percent of the surface of the oceans, the large coastal upwelling areas on the eastern edges of the Pacific and the Atlantic are among the most biologically productive marine areas of all.

What is productivity in the ocean?

What is Ocean Productivity? Ocean productivity largely refers to the production of organic matter by "phytoplankton," plants suspended in the ocean, most of which are single-celled. ... Therefore, SP in the ocean is small in comparison to NPP.

What is ocean productivity quizlet?

productivity. The amount of biological material (usually expressed as carbon) produced per unit time (usually expressed per unit of area in the ocean) biomass.

How is primary productivity measured in an aquatic environment?

Primary productivity is considered in terms of its evolution from measures of standing crop and yield, which have been gradually replaced by measures of rate of carbon uptake or oxygen production, or by measure of nutrient loss, or by change of COa in the environment.

What is the reason for low productivity of ocean?

In ocean, there is insufficient radiation as sunlight decreases with the increasing depth which decreases the rate of photosynthesis. Decrease in rate of photosynthesis decreases the growth of aquatic plants and animals. Minerals and nutrients can also be a retarding factor based on location of the oceans.

What is the productivity of the open ocean?

The average ocean productivity is about 50 grams carbon per square meter per year. The productivity of the open ocean (ocean away from coasts) is comparable to desert production. This means that most of the ocean, or about 90%, is essentially desert.

Do tropical oceans have high productivity?

The surface water is always warm and there is always a pronounced thermocline, leading to highly stratified water that prevents the nutrient-rich bottom water from reaching the surface (section 6.2). Thus productivity in tropical water is always nutrient-limited, and productivity is low throughout the year (Figure 7.4.

What factors affect productivity productivity?

Technical factors: Productivity largely depends on technology. Technical factors are the most important ones. These include proper location, layout and size of the plant and machinery, correct design of machines and equipment, research and development, automation and computerization, etc.

What is productivity in environmental science?

In ecology, productivity is the rate at which energy is added to the bodies of organisms in the form of biomass. ... Productivity can be defined for any trophic level or other group, and it may take units of either energy or biomass. There are two basic types of productivity: gross and net.

How is productivity defined quizlet?

Productivity is defined as the. amount of goods and services produced from each unit of labor input.

What are the factors of productivity quizlet?

--Capital resources, their availability, and the efficiency of factories and equipment.

What is productivity and how is it calculated quizlet?

Productivity is the amount and value of goods and services (outputs) produced from set amounts of resources (inputs). It measures how efficiently the inputs are converted into outputs in a set time period. ... or by dividing production into small tasks that can be done by different workers.
