Two opposite forces operate in the growth and development of every population. One of them relates to the ability to reproduce at a given rate. The force opposite to it is called:

In which phase is the maximum growth rate observed?

The integral form of the exponential growth equation is $N_{t} = N_{0} e^{rt}$. Identify $A, B, C$,and $D$ from the given equation where:
$A$: Population density after time $t$
$B$: Population density at time zero
$C$: Intrinsic rate of natural increase
$D$: The base of natural logarithms $(2.71828)$

When births are equal to deaths,it is called:

"In the absence of environmental resistance, the population grows in a geometrical ratio when the food is given in an arithmetical ratio." This is:

The formula for exponential population growth is
