of these.Population
size The size of a
population depends upon several factors like mortality, natality, etc. The
size in nature could be as low as less than 10 (Siberian cranes at Bharatpur
wetlands in any year) or go in million (Chlamydomonas in a pond).Population
size, more technically called population density (designated as N) need not
necessarily be measured in numbers only. Although the total number is the
most appropriate measure of population density. But in some cases in is
different to determineFor
exampleIn
a forest area suppose there are 200 Parthenium plants but only a
single banyan tree will huge canopyThe
following inference could be made(i)
Population density of banyan is low(ii)
Population cover area of banyan to highIn
this example percentage of cover of biomass is more meaningful than
population size |
and is single banyan tree. Which of
the conculsion (s) is/are correct?I.
Population density of banyan is lowII.
Population cover area of banyan is highIII. In
above cases the percentage of cover of biomass is more meaningful than
population size
