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.
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]
The fraction of that energy that is converted into glucose reflects the gross productivity of the blade of grass. The energy remaining after respiration is considered the net primary production. In general, gross production refers to the energy contained within an organism before respiration and net production the energy after respiration.

The phase of the Moon does not influence fertility, cause a fluctuation in crime, or affect the stock market. There is no correlation between the lunar cycle and human biology or behavior. However, the increased amount of illumination during the full moon may account for increased epileptic episodes, motorcycle accidents, or sleep disorders.
A farmer can invest a large amount of money to increase his yields by a few percent, for example with an extremely expensive fertilizer, but if that cost is so high that it does not produce a comparative return on investment, his profits decline, and the higher yield can mean a lower agricultural productivity in this case. A yield is a 'partial ...
Agricultural productivity is measured as the ratio of agricultural outputs to inputs. [1] While individual products are usually measured by weight, which is known as crop yield , varying products make measuring overall agricultural output difficult.
There are two main standards of thought on economic efficiency, which respectively emphasize the distortions created by governments (and reduced by decreasing government involvement) and the distortions created by markets (and reduced by increasing government involvement).
