A population of arctic birds has migrated farther north than previous years. The new location is good for the birds, and the population exhibits exponential growth. As time passes, the population begins to level out and maintain a steady population size. (10 points)
At the constant birth rate in Population through time and is never be limited by food or disease is known as Exponential Groth.The formula for Exponential Growth=dNdt=rNdNdt=rN where dNdt is the rate of change in population size r is the biotic potentialand N is the population size.
if lambda>1 means there is an increase in population.
Value of r can be calculated by the equation
r= Birth-Death/ Actual population
here it is birth=200
Actual population=2000 so r= 200-100/2000
ie r is positive and greater than 0 .it means that population is increasing.
Density -independent population size regulator for these birds are weather and cimate,exert their influences on population size regardless of the population's density.
