The primary productivity or "bottom up" hypothesis suggests that plant growth is limited by the energy available to plants which is determined in turn by temperature and precipitation. Additional plant growth means more forage is available--thus herbivores, and ultimately carnivores, should increase in abundance.

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.
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 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.
What is the difference between Gross Primary Productivity (GPP) and Net Primary Productivity (NPP)?
Gross Primary Productivity (GPP) is the total amount of energy that plants capture through photosynthesis, while Net Primary Productivity (NPP) is the amount of energy that plants store after accounting for the energy they use for their own growth and metabolism. In other words, GPP is the total production of plants, while NPP is the amount of energy available for consumption by other organisms in the ecosystem.
What is the gross primary productivity equation used to calculate the rate at which plants convert solar energy into chemical energy through photosynthesis?
The gross primary productivity equation used to calculate the rate at which plants convert solar energy into chemical energy through photosynthesis is: Gross Primary Productivity Rate of Photosynthesis - Rate of Respiration.
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.
What is the primary hypothesis for the extinction of large mammals such as mammoth?
The primary hypothesis is that they were led to extinction by hunting by humans.
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.
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.
