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.
In the book's introduction, Bauer raises several questions which are examined in subsequent chapters. These questions are about the distinction between "productivity" and "creativity" (commonly understood as word-formation via, respectively, unconscious or semiconscious application of rules, and deliberate coining), the possibility of developing measures for productivity, the relationship ...
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]
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
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.

A biologist conducting research in a biotechnology laboratory. Biotechnology is a multidisciplinary field that involves the integration of natural sciences and engineering sciences in order to achieve the application of organisms and parts thereof for products and services. [1]
A person simultaneously making use of a laptop and mobile phone. Human multitasking is the concept that one can split their attention on more than one task or activity at the same time, such as speaking on the phone while driving a car.
Productive efficiency of an industry requires that all firms operate using best-practice technological and managerial processes and that there is no further reallocation that bring more output with the same inputs and the same production technology. By improving these processes, an economy or business can extend its production possibility ...
