(l). Primary Productivity of Plants A proportion of the energy of gross primary productivity is used by plants in a process called respiration. Respiration provides a plant with the energy needed for various plant physiological and morphological activities.The general equation for respiration is:igure 9l-1: Inputs and outputs of the photosynthetic process. The primary productivity of a community is the amount of biomass produced through photosynthesis per unit area and time by plants, the primary producers.

Productivity For a single input this means the ratio of output (value-added) to input. When multiple inputs are considered, such as labor and capital, it means the unaccounted for level of output compared to the level of inputs. This measure is called in macroeconomics Total Factor Productivity TFP or Multi Factor Productivity MFP.abor productivity is the value of goods and services produced in a period of time, divided by the hours of labor used to produce them. In other words labor productivity measures output produced per unit of labor, usually reported as output per hour worked or output per employed person.

Productivity Productivity is one of the main concerns of business management and engineering. Many companies have formal programs for continuously improving productivity, such as a production assurance program. Whether they have a formal program or not, companies are constantly looking for ways to improve quality, reduce downtime and inputs of labor, materials, energy and purchased services.

- Net Primary Productivity. Download a Quicktime animation of this dataset (6 MB). Plants capture and store solar energy through photosynthesis. During photosynthesis, living plants convert carbon dioxide in the air into sugar molecules they use for food. In the process of making their own food, plants also provide the oxygen we need to breathe. Thus, plants provide the energy and air required by most life forms on Earth.

- Primary Productivity. The flow of energy through any ecosystem starts with the fixation of sunlight by plants and other autotrophic organisms. In this way the plant accumulates energy and this energy is called primary production. The rate at which this energy accumulates is called primary productivity.

productivity A measure of the efficiency of a person, machine, factory, system, etc., in converting inputs into useful outputs. Productivity is computed by dividing average output per period by the total costs incurred or resources (capital, energy, material, personnel) consumed in that period. Productivity is a critical determinant of cost efficiency. Use productivity in a sentence. Knowing the productivity levels of all of your employees will help you to figure out who to keep and who to let go. The productivity of the individual was unmatched in the department so we decided to keep him during the lay offs.

Productivity (ecology) In ecology, productivity refers to the rate of generation of biomass in an ecosystem. It is usually expressed in units of mass per unit surface (or volume) per unit time, for instance grams per square metre per day (g m−2 d−1). The mass unit may relate to dry matter or to the mass of carbon generated.
