explain with the help of an example how the percentage cover is a more meaningful measure of population size than mere numbers.

Answer»

(i) Measurement of POPULATION in habitat DETERMINES the RELATIVE abundance of a particular species and its effect on the available resources of that particular habitat.
(ii) The PERCENTAGE cover is rrtore meaningful measure of population size than mere NUMBERS because the relative abundance of a species is not only determined by number of individuals but by the relative abundance in both biomass and number. e.g. in a unit area the number of grass species or relative abundance in number is high but not the relative biomass, if the same area has one or two Ficus bengalensis tree, it is very low in relative abundance of number but high in relative abundance of biomass.
