Distribution occurs when the trading volume of a security is greater than that of the previous day without any price increase. Scientists gain additional insight into a species’ biology and ecology from studying how individuals are spatially distributed. Definition: Distribution means to spread the product throughout the marketplace such that a large number of people can buy it. The second definition, which is perhaps the most commonly repeated, considers ecology to be the study of the distribution and abundance of organisms (Andrewartha and Birch 1954). The distribution of the observations around the mean is very precisely defined as: A good transport system to take the goods into different geographical areas. Distribution definition, an act or instance of distributing. Biology Forums - Study Force is the leading provider of online homework help for college and high school students. Transects and quadrats are used to collect quantitative data. Distribution definition is - the act or process of distributing. distribution [dis″trĭ-bu´shun] 1. the specific location or arrangement of continuing or successive objects or events in space or time. Both affect diversity and distribution. Abiotic factors are non-living variables. 2. the extent of a ramifying structure such as an artery or nerve and its branches. How to use distribution in a sentence. The third definition focuses ecology on the study of ecosystems (Odum 1971). Its familiar bell-shaped curve is ubiquitous in statistical reports, from survey analysis and quality control to resource allocation. 3. the geographical range of an organism or disease. The distribution of organisms in a habitat may be affected by physical factors, such as temperature and light. The normal distribution is clearly a symmetrical distribution, but not all symmetrical distributions can be considered to be normal. Biotic factors are the interactions between organisms. Normal distribution, the most common distribution function for independent, randomly generated variables. Density and size are useful measures for characterizing populations. While all 3 of the above distributions may appear different, they are, in fact, all identical in one regard. Range of an organism or disease the third definition focuses ecology on Study!
