Given below are two statements, statement I and statement II.

Statement-I : Measurement and comparison of total growth per unit time is called relative growth rate.

Statement-II : A sigmoid growth curve is characteristic of organisms growing in a natural environment.

In light of the given statements, choose the correct answer from the options given below.

Statement-I is incorrect. Measurement and comparison of total growth per unit time is called the absolute growth rate. The growth of the given system per unit time expressed on a common basis, e.g., per unit initial parameter is called the relative growth rate.

Statement-II is true. A sigmoid growth curve, with distinct phases of exponential growth, slowing growth, and eventual stabilization, is characteristic of organisms growing in natural conditions.
