Select an incorrect statement :

Options

A. Natality refers to the number of births during a given period
B. If a new habitat is just being colonised , emigration may contribute more significantly to population growth than birth rates
C. In 1981, the r value for human population in India was 0.0205
D. Any species growing exponentially under unlimited resource conditions can reach enormous population densities in a short time.

Answer

To solve the question of selecting an incorrect statement, we will analyze each of the provided statements one by one.

### Step-by-Step Solution:

1. **Statement 1: Natality refers to the number of births during a given period.**
- **Analysis:** This statement is correct. Natality, also known as birth rate, is defined as the number of live births in a population during a specific time period.

2. **Statement 2: If a new habitat is just being colonized, immigration may contribute more significantly to population growth than birth rate.**
- **Analysis:** This statement is incorrect. In a newly colonized habitat, the population growth is primarily influenced by the birth rate rather than immigration. If individuals are leaving their original habitat (emigration), it would not contribute positively to the population growth in the new habitat. Thus, this statement is incorrect.

3. **Statement 3: In 1981, the R value of the human population in India was 0.0205.**
- **Analysis:** This statement is correct. The R value, or the intrinsic rate of natural increase, represents the growth rate of a population. The value of 0.0205 for India in 1981 is accurate.

4. **Statement 4: Any species that grows exponentially under unlimited resource conditions can reach enormous population densities in a short time.**
- **Analysis:** This statement is also correct. Exponential growth occurs when resources are unlimited, allowing a species to reproduce rapidly and reach high population densities quickly.

### Conclusion:
The incorrect statement is **Statement 2**: "If a new habitat is just being colonized, immigration may contribute more significantly to population growth than birth rate."
