The measure of the maximum rate of reproduction under optimal conditions is known as:

If the population density at time $t$ is $N_t$,then the population density at time $t+1$ is given by:

Give scientific reasons: When a plant culture is grown in a limited amount of nutrient medium,growth is slow in the initial stage (lag phase). It increases rapidly in the exponential phase and again slows down in the stationary phase.

In a growing population of a country,

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:

What are the factors affecting population growth?
