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
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.
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.
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.
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 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.
How can primary productivity be increased?
Primary productivity can be increased by providing more sunlight, nutrients, and carbon dioxide to photosynthetic organisms like plants. Removing limiting factors such as competition, herbivory, or pollutants can also increase primary productivity. Additionally, optimizing environmental conditions like temperature and water availability can help stimulate the growth of primary producers.
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.
