(a) What is "population" according to you as a biology student?
(b) "The size of a population for any species is not static parameter". Justify the statement with specific reference to functions in the population density of a region in a given period of time.
(a) A population is a group of individuals of a particular species which live in a well defined geographical area, share or compete for similar resources and potentially interbreed.
(b) The size of a population for any species is not a static parameter. It keeps charging in time, depending on various factors including food availability, predation pressure, and adverse weather.
The density of population in a given area flourishes or declines due to the changes in these four processes –
NATALITY and IMMIGRATION contribute to the increase in population and density and MORTALITY and EMIGRATION to a decrease in population.
