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 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.

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.
