If in a population of size 'N' the birth rate is represented as 'b' and the death rate as 'd' , the increase or decrease in 'N' during a unit time period 't' will be:
`(dN)/(dt) = (b - d) xx N`
The equation given above can also be represented as :
`(dN)/(dt) = r xx N `, where `r = (b - d)`
What does 'r' represent ? Write any one significance of calculating 'r' for any population.

Explanation

To solve the question regarding the representation of 'r' in the population growth equation, let's break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Equation**:
The equation given is:
\[
\frac{dN}{dt} = (b - d) \times N
