How are gross and net primary productivity of a community related?
Gross Primary Productivity- Total amount of chemical energy stored by photosynthesis. Net Primary Productivity- Remaining energy, which is available to the consumers as food.
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.
What traits of an ecosystem does primary productivity measure?
The rate at which the ecosystem produces chemical energy from sunlight.
How is productivity of an ecosystem measured?
Ecosystem energy budget`s depend primarily of autotroph`s such as photoautotrophic organisms. The budget (energy that can be used by energy flux) depends on these primary producers for the rest of the food webs.
Where will you locate on a pendulum or roller coaster the greatest potential and greatest kinetic energy?
On a pendulum, the greatest potential energy is at the highest point of the swing on either side, and the greatest kinetic energy is at the bottom of the swing. On a roller coaster, the greatest potential energy is at the top of a hill, and the greatest kinetic energy is at the bottom of the hill.
The amount of organic material that the autotrophic organisms of an ecosystem produce?
primary productivity.

What traits of an ecosystem does primary productivity measure?
The rate at which the ecosystem produces chemical energy from sunlight.
What is the difference between gross primary productivity and net primary productivity?
Gross primary production consists of the amount of light energy that is converted to chemical energy by photosynthesis per unit of time. This chemical energy is going to two places-- respiration and growth of new biomass. Net primary production omits the energy used in respiration... just the energy going to new plant growth. Mathematically: (R = respiration) NPP = GPR - R
What is the primary productivity hypothesis?
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.
Why does the level of primary productivity increases at the equatorial approach?
The theory that the level of primary productivity increases at the equatorial approach is relatedÊto what is called theÊlatitudinal diversity gradient. Basically, it occurs because the numbers of species are higher near the tropic zone than at the poles. There is an increase in solar energy at lower latitudes orÊthe equator that causes an increase in net primary productivity or photosynthesis. With more plants availability at lower latitudes, more species can be supported in these regions.
What is biological productivity?
Biological productivity is how much energy or mass is produced by the members of an ecosystem. There are two types of biological productivity: primary production, in which organisms create organic material from inorganic materials through autotrophy; and secondary production, in which organic material is created from other organic material through heterotrophy.
What is the difference between net productivity and gross productivity?
Gross primary production consists of the amount of light energy that is converted to chemical energy by photosynthesis per unit of time. This chemical energy is going to two places-- respiration and growth of new biomass. Net primary production omits the energy used in respiration... just the energy going to new plant growth. Mathematically: (R = respiration) NPP = GPR - R
Which factor would have the greatest effect on the flow of energy into an ecosystem?
Ecological balance is automatic function of nature. When it is saturated by human due to various reasons, the ill effects of it are experienced in the form of natural disasters and incurable diseases. the earth becomes a violent planet. we have to face the wrath of nature.
How is primary productively related to biomass?
Producers store chemical energy in the biomass, also known as organic material, and the rate by which producers in an ecosystem build biomass is primary productivity. Both dealing with building biomass by the action caused by producers. Hope this helps (:
Is geothermal energy a primary or secondary energy source?
primary
