Relative density: relative density is the study of numerical strength of a species in relation to the total number of individuals of all the species relative frequency. The degree of dispersion of individual species in an area in relation to the number of all the species occurred. Relative dominance.

Answer» ve starts flattening or shows only a steady INCREASE (Fig. 67 B) at one POINT in the graph.Results:The point of the graph, at which the curve starts flattening or shows only a steady or gradual increase, indicates the minimum size or minimum area of the quadrat suitable for study.2. Aim of the Experiment:To study communities by quadrat method and to determine % FREQUENCY, DENSITY and Abundance.Requirements:Metre scale, string, four nails or quadrat, notebook.(i) Frequency:Frequency is the number of sampling units or quadrats in which a given species occurs.I HOPE this will help youIf not then comment me |
