The productivity of autotrophs, such as plants, is called primary productivity, while the productivity of heterotrophs, such as animals, is called secondary productivity. [ 1 ] The productivity of an ecosystem is influenced by a wide range of factors, including nutrient availability, temperature, and water availability.
Tests of sufficiency in biology are used to determine if the presence of an element permits the biological phenomenon to occur. In other words, if sufficient conditions are met, the targeted event is able to take place. However, this does not mean that the absence of a sufficient biological element inhibits the biological event from occurring.
This course is designed for students who wish to pursue an interest in the life sciences. The College Board recommends successful completion of high school biology and high school chemistry [2] before commencing AP Biology, although the actual prerequisites vary from school to school and from state to state.
Gross primary productivity is the amount of energy the producer actually gets. [ 13 ] [ 14 ] Generally, 60% of the energy that enters the producer goes to the producer’s own respiration. [ 12 ] The net primary productivity is the amount that the plant retains after the amount that it used for cellular respiration is subtracted. [ 13 ]
Productivity is the efficiency of production of goods or services expressed by some measure. Measurements of productivity are often expressed as a ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time.

The International Biological Program (IBP) was an effort between 1964 and 1974 to coordinate large-scale ecological and environmental studies.Organized in the wake of the successful International Geophysical Year (IGY) of 1957–1958, the International Biological Program was an attempt to apply the methods of big science to ecosystem ecology and pressing environmental issues.
Enzyme activity is a measure of the quantity of active enzyme present and is thus dependent on various physical conditions, which should be specified. It is calculated using the following formula:
The sources of productivity growth and production volume growth are explained as follows. Productivity growth is seen as the key economic indicator of innovation. The successful introduction of new products and new or altered processes, organization structures, systems, and business models generates growth of output that exceeds the growth of ...
