Quantitative comparisons between the growth of the living system can be made in two ways: (i) Measurement and the comparison of total growth per unit time is called the . . . . a . . . . growth rate. (ii) The growth of the given system per unit time expressed on a common basis, eg.; per unit initial parameter is called . . . b . . . . growth rate.

Step-by-step solution

Quantitative comparisons between the growth of living system can also be made in two ways : (i) measurement and the comparison of total growth per unit time is called the absolute growth rate. (ii) 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.
