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 else can I help you with?
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 .
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.
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.
What is auxilary hypothesis?
An auxiliary hypothesis is a supplementary assumption or proposition that is added to a primary hypothesis in order to support it or make it testable. It often includes conditions or factors that are presumed to be true for the main hypothesis to hold. These auxiliary hypotheses can be critical in scientific testing, as they help clarify the implications of the primary hypothesis and can influence the interpretation of experimental results. However, they can also introduce additional complexity, as their validity affects the overall conclusions drawn from the primary hypothesis.
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 is Primary homology?
proposed hypothesis of homology based on similarity.
