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.

The amount of organic material that the autotrophic organisms of an ecosystem produce?
primary productivity.
What part of the organization has primary responsibility of productivity?
The manager
What biome has the highest primary production in terrestrial ecosystems?
Tropical rain forests have the highest primary productivity of any ecosystem on the planet.
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 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 .
The amount of organic material that the autotrophic organisms of an ecosystem produce?
primary productivity.
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.
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 can primary productivity be increased?

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 is production carried out by plants during photosynthesis, and water is the only hydrogen donour in cyclic and noncyclic phosphorelation of photosynthesis
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.
What part of the organization has primary responsibility of productivity?
The manager
What is the gross primary productivity minus the respiration rate of producers?
net
What has an immediate effect on net primary productivity?
light temperature, and precipitation
