Population evolve to maximise their reproductive fitness also called Darwinian fitness with
High $r$ value
Low $r$ value
High $K$ value
High $\frac{K-N}{K}$ value
With the help of suitable diagram describe the logistic population growth curve.
Maximum survival and reproductive capacity shown by a population under optimal environmental conditions is called
The primary cause behind rapidly growing population of the world in recent times is
If a population growing exponentially double in size in $3$ years, what is the intrinsic rate of increase $(r)$ of the population?
A biologist studied the population of rats in a barn. He found that the average natality was $250$, average mortality $240$, immigration $20$ and emigration $30$. The net increase in population is
