What is productivity in temperate oceans determined by?
Productivity in temperate oceans is determined by factors such as nutrient availability, light levels, temperature, and water movement. These factors influence the growth of phytoplankton, which forms the base of the food chain in marine ecosystems. Phytoplankton productivity supports the productivity of higher trophic levels in the ocean.
How zooplankton controls the growth of phytoplankton?
Zooplankton can control the growth of phytoplankton by grazing on them, reducing their population. This grazing pressure can influence the size and composition of phytoplankton communities. By consuming phytoplankton, zooplankton can also regulate nutrient cycling and ecosystem productivity in aquatic environments.
What has the author Brian E Cole written?
Brian E. Cole has written: 'Phytoplankton productivity, respiration, and nutrient uptake and regeneration in the Potomac River, August 1977 - August 1978' -- subject(s): Phytoplankton
What is the idea behind the age limits?
The idea behind the age limits is to give everyone an equal chance and ensure productivity.
Which organisms are responsible for the majority of the net primary productivity in shallow marine waters?
Phytoplankton, particularly diatoms and dinoflagellates, are responsible for the majority of net primary productivity in shallow marine waters. These microscopic organisms play a key role in the marine food web, converting sunlight into organic matter through photosynthesis.

Why is the productivity of the oceanic zone is high even though nutrient levels are low?
The productivity of the oceanic zone is high due to the presence of phytoplankton that can efficiently photosynthesize with available sunlight. Additionally, oceanic currents can bring nutrients from deeper waters to support phytoplankton growth. In regions such as upwellings, nutrients like nitrogen and phosphorus are brought to the surface, further enhancing productivity despite low nutrient levels.
Do phytoplankton need sunlight?
Yes, phytoplankton need sunlight for photosynthesis, the process by which they convert sunlight into energy to grow and reproduce. Sunlight is essential for their survival and productivity in the ocean.

H Cohen has written: 'Phytoplankton dynamics of the fresh, tidal Potomac River, Maryland, for the summers of 1979 to 1981' -- subject(s): Ecology, Phytoplankton, Algae, Vegetation dynamics 'Primary productivity by phytoplankton in the tidal, fresh Potomac River, Maryland, May 1980 to August 1981' -- subject(s): Phytoplankton
How does the spring season affect the plankton?
In the spring season, increased sunlight and warmer temperatures lead to the growth of phytoplankton. This increase in phytoplankton can then support the growth of zooplankton, which feed on the phytoplankton. Overall, the spring season can enhance plankton productivity and contribute to the overall marine food chain.

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.
