What traits of an ecosystem does primary productivity measure?
The rate at which the ecosystem produces chemical energy from sunlight.
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.
Secondary productivity in an ecosystem?
Primary productivity tells you how productive an ecosystem will be. It is the rate at which chemical energy is produced from sunlight, which determines the maximum amount of energy available to all higher trophic levels in an ecosystem.
Which marine ecosystem has the fewest available nutrients and the lowest productivity?
open oceans
What is the primary productivity rate at which producers in an ecosystem carry on photosynthesis to make carbohydrates?
Gross
What traits of an ecosystem does primary productivity measure?
The rate at which the ecosystem produces chemical energy from sunlight.
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 ecologically productive?
Ecological productivity refers to the capacity of an ecosystem to produce biomass through photosynthesis and nutrient cycling. It is a measure of the amount of energy that flows through the ecosystem and is vital for supporting biodiversity and ecological services. High ecological productivity often indicates a healthy and sustainable ecosystem.
What happens to productivity as rainfall increases?
Productivity decreases as rainfall increases. Marine life tend to be more productive when there is less rainfall in their ecosystem.
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.
How is primary productivity measured in an ecosystem?
Primary productivity in an ecosystem is typically measured by calculating the amount of energy or biomass produced by plants through photosynthesis. This can be done by measuring the rate of oxygen production, tracking the growth of plant biomass, or using remote sensing techniques to estimate plant productivity.
What is the primary productivity rate at which producers in an ecosystem carry on photosynthesis to make carbohydrates?
Gross
How is energy lost after gross primary productivity (GPP) occurs in an ecosystem?
After gross primary productivity (GPP) occurs in an ecosystem, energy is lost through processes such as respiration, heat loss, and consumption by other organisms. This results in a decrease in the amount of energy available for further growth and development within the ecosystem.
If the variety of species in an ecosystem decreases this is a decrease in the system's?
biodiversity
Equals the gross primary productivity minus the respiration rate of producers?
Net primary productivity is the amount of energy that remains in an ecosystem after accounting for the energy used by producers (plants) for respiration. It is calculated by subtracting the respiration rate of producers from the gross primary productivity. This remaining energy is available for consumers in the ecosystem to use for growth and reproduction.
