how is primary productivity measured

* MEASUREMENT OF PRIMARY PRODUCTIVITY:- AQUATIC ECOSYSTEM Presented to: Presented by: Dr. S.SUNDARAMOORTHY Narpat Singh Prof. Msc. It is based upon the assumption that the amount of oxygen produced is proportional to gross production because one molecule of oxygen is produced for each atom of carbon fixed. The decrease in dissolved oxygen (DO) in the dark bottle over time is a measure of the rate of respiration. Whether one measures the rate at which photosynthesis occurs, or the rate at which the individual plant increases in mass, one is concerned with primary production (definition: the synthesis and storage of organic molecules during the growth and reproduction of photosynthetic organisms). In this method, a sample of water is placed into two bottles. Productivity is usually measured as the rate at which energy or biomass is produced per unit area per unit time. Productivity, measured by gross and net primary productivity, is defined as the amount of energy that is incorporated into a biomass. Measurement of primary productivity 1. One bottle is stored in the dark and the other in a lighted area. Productivity stands for the total increase in the mass (phytomass). One method of measuring the production of oxygen is the light and dark bottle method. • Measures gross and net primary production • Relatively “easy” to measure Several caveats: • 1) assumes rate of respiration in dark = light. Primary goods: Primary goods are any goods that are farmed foods and raised animals. At its simplest, labour productivity is the amount of output per worker. Learning Objectives Explain the concept of primary production and distinguish between gross primary production and net primary production This method is employed to measure primary productivity in an aquatic ecosystem such as a pond. The more they produce, the more they contribute to profits for the company. Classical method :- i. The productivity of a factory worker making footballs, for example, could be measured by how many footballs they make in one hour. Various light dependent oxygen consuming pathways (Mehler reaction and photorespiration) • 2) requires incubation and confinement of samples. Daniel G. Milchunas, Biases and Errors Associated with Different Root Production Methods and Their Effects on Field Estimates of Belowground Net Primary Production, Measuring Roots, 10.1007/978-3-642-22067-8, (303-339), (2012). Samples of water from different depths are placed in paired bottles. Main Difference. *Measurement of primary productivity in aquatic system measurement are two types:- 1. 3rd sem 2. What does primary productivity measure? Only respiration can occur in the bottle stored in the dark. primary productivity OVERVIEW: Primary production is estimated from 14 C uptake using a simulated in situ technique in which the assimilation of dissolved inorganic carbon by phytoplankton yields a measure of the rate of photosynthetic primary production in the euphotic zone.
