Population growth is reduced by environmental resistance. This phase is known as:

What are the factors affecting population growth?

The logistic population growth is expressed by the equation:

Phase of accelerated growth of logistic growth curve is . . . . . . .

Any species growing $A$ under unlimited resource conditions can reach enormous population densities in a short time. Darwin showed how even $B$ growing animal like elephant could reach enormous numbers in absence of check and that characteristics of organism is called $C$. Choose the correct option for $A, B$ or $C$ respectively.

Ecological factors which prevent a species from producing at its maximum rate is termed as
