Question

Describe briefly: Absolute and relative growth rates.

Answer 1

The growth of the given system per unit time expressed on a common basis is called as Relative growth rate. For example: ... Though the absolute growth rates both the leaves is the same, the relative growth rate in leaf X is faster.

Answer 2

The absolute growth rate can be defined as the measurement and comparison of total growth per unit time, while the relative growth rate is the growth of the given system per unit time.

For example:

Two leaves A and B having different sizes  5cm and 40 cm show exact absolute increase in the area in the given time.

Assume that both the leaves have grown by 5 cm2 in a day.

Though the absolute growth rates of both the leaves is the same, the relative growth rate in leaf A is faster.
