Hint: The density of the population is expressed in terms of biomass per unit area or unit volume. It may be expressed in terms of the amount of above- ground plant biomass. Population density refers to the number of individual organisms of a species living together in a unit area or unit volume.

In an area, if there are 200 Parthenium plants but only a single Banyan tree with a large canopy. It states that the population density of Banyan is low relative to that of Parthenium amounts to underestimating the enormous role of Banyan in that community. The mass of a particular organism or organism present at a particular time within a defined area, i.e. the total Biomass of the organism or organisms. In such cases standing crop, the percent is a more meaningful measure of the population density. Biomass is plant or animal material used for energy production, or in various industrial processes as a raw substance for a range of products. Standing Crop refers to the amount of biomass at a given time. Usually refers to the amount of above-ground plant biomass.
