Photosynthetic productivity in polar areas is limited by factors such as low light availability due to long periods of darkness in winter, cold temperatures that slow down metabolic processes, and limited nutrient availability in the soil. Additionally, snow and ice cover can physically obstruct sunlight from reaching plants, further limiting photosynthesis.
What else can I help you with?
When do you use a polar map?
Polar maps are typically used to represent areas near the poles, where distortion is minimized. They are useful for navigation, meteorology, and polar research.
Where does the polar easterlies occur?
The polar easterlies occur between 60 and 90 degrees latitude in both the Northern and Southern Hemispheres. They are cold winds that blow from the polar high-pressure areas towards lower pressure areas at mid-latitudes.
Why is productivity high in polar oceans?
Productivity in polar oceans is high primarily due to the availability of nutrient-rich waters that are brought to the surface through processes like upwelling and mixing driven by wind and currents. The extended daylight during summer months enhances photosynthesis among phytoplankton, which serve as the base of the food web. Additionally, cold water holds higher concentrations of dissolved oxygen, supporting diverse marine life. These factors combined create a conducive environment for high biological productivity in polar regions.
What is sometimes observed in the polar areas of mars and what do scientists think this is?
White polar caps. Frozen carbon dioxide and water ice.
Air currents that blow near the north and south poles are the?
Polar easterlies. They are cold, dry winds that blow from the polar high-pressure areas towards lower latitudes.
What is Lowest net primary productivity?
The lowest net primary productivity usually occurs in extreme environments such as deserts, polar regions, and deep ocean gyres where there is limited access to sunlight, water, and nutrients for photosynthesis. These areas have low plant growth and biomass production, resulting in low net primary productivity.
During which season does primary productivity reach its peak in polar oceans?
Primary productivity in polar oceans typically reaches its peak during the summer season when there is continuous sunlight due to the polar day. This allows phytoplankton and other primary producers to photosynthesize and grow rapidly, leading to increased productivity.
Where are the earth's polar areas?
The earth's polar areas are at ARCTIC to the north and ANTARCTIC to the south of the equator.
Why is the polar region important for lumbering?
There are no trees in polar areas so the answer is no.
What are winds that flow from the horse latitudes toward that polar areas?
Polar Easterlies
What type of air mass come from polar ocean areas?
cold and moist air mass comes from polar ocean areas
Can polar bears live in warm areas?
No.
Dry areas found in polar regions that have long cold winters and cool summers?
These dry areas in polar regions are known as polar deserts. These regions experience low precipitation levels and cold temperatures due to the polar climate. Their cold winters and cool summers contribute to the dry conditions in these areas.
Where is primary production the least?
Primary production is typically the least in areas with extreme environmental conditions, such as deserts and polar regions, where limited sunlight, water, and nutrients restrict plant growth. Additionally, deep ocean waters and areas with heavy pollution may also experience low primary production due to nutrient scarcity and unfavorable conditions for photosynthetic organisms.
Which is more polar- chlorophyll a or b?
Chlorophyll a is more polar than chlorophyll b due to the presence of a methyl group in chlorophyll b that increases its overall hydrophobicity, making it less polar compared to chlorophyll a. Consequently, chlorophyll a has a higher affinity for polar solvents and is the primary photosynthetic pigment in plants.
How are Antarctica and the Arctic similar?
Both areas are polar.
How are polar and desert areas alike?
there both deserts
