What is the difference between net primary productivity and primary productivity?
primary productivity is defined as the amount of . organic matter produced per unit area over a time period by plant during photosynthesis. and gross primary productivity minus respiration losses is the net primary productivity .
How are gross and net primary productivity of a community related?
Gross primary productivity is the total amount of energy captured by producers through photosynthesis, while net primary productivity is the amount of energy left after subtracting energy used for respiration. Net primary productivity is thus derived from gross primary productivity, as it represents the energy available to consumers in the community after accounting for producers' own energy needs.
Which biome has a high primary productivity?
do
In an aquatic ecosystem the algae and phytoplankton are responsible for primary productivity. All BUT ONE factor usually influences the primary productivity of a marine ecosystem. That is?
In a marine ecosystem, primary productivity is influenced by factors such as light availability, nutrient concentration, and temperature. However, the salinity of the water typically does not directly influence primary productivity in the same way. While extreme salinity can affect the types of organisms present, it is not a primary determinant of productivity like the other factors mentioned.
Can you use primary productivity in a sentence?
One sentence with the primary productivity is: The companies focus was on the primary productive. This focus ensures all employees put the task at hand at the forefront.
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.
How is primary productivity limited by water?
Primary productivity can be limited by water availability in terrestrial ecosystems, as water is needed for photosynthesis to occur. In aquatic ecosystems, primary productivity can also be limited by water availability, as light penetration can be reduced in murky waters, limiting the amount of photosynthesis that can take place. Additionally, drought conditions can directly reduce primary productivity in both terrestrial and aquatic ecosystems.
What is the gross primary productivity formula used to calculate the amount of energy produced by plants through photosynthesis in an ecosystem?
The gross primary productivity formula is: Gross Primary Productivity Rate of Photosynthesis - Rate of Respiration. This formula calculates the amount of energy produced by plants through photosynthesis in an ecosystem.
What are the primary determinants of agricultural labor productivity?
The primary determinants of agricultural productivity would be farm size, age, the weather and labor costs. Output is also considered a determinate.
Can you provide an example of gross primary productivity in an ecosystem?
An example of gross primary productivity in an ecosystem is the process of photosynthesis in plants, where they convert sunlight into energy to produce food for themselves.
What factors other than water might effect primary productivity?
Primary productivity can be influenced by several factors beyond water availability, including nutrient levels (such as nitrogen, phosphorus, and potassium), sunlight exposure, and temperature. The presence of carbon dioxide also plays a crucial role, as it is essential for photosynthesis. Additionally, human activities, such as pollution and land use changes, can alter ecosystems and impact productivity. Finally, competition among species for resources can further affect the overall productivity of an ecosystem.
What limits primary productivity in tropical oceans?
Primary productivity in tropical oceans is primarily limited by nutrient availability, particularly nitrogen and phosphorus. Factors such as temperature, light availability, and water movement can also influence primary productivity in tropical oceans. Upwelling events that bring nutrient-rich waters to the surface can enhance primary productivity in these regions.
