The formula for exponential population growth is

Options

A. Environmental resistance
B. Reproductive potential
C. Growth rate
D. Carrying capacity

Answer

**Step-by-Step Text Solution:**

1. **Understanding Exponential Population Growth:**
- Exponential population growth occurs when a population increases rapidly due to abundant resources. This growth is characterized by a constant growth rate and is typically represented mathematically.

2. **Identifying the Formula:**
- The formula for exponential population growth is expressed as:
\[ \frac{dn}{dt} = r \cdot n \]
- In this formula:
- \( \frac{dn}{dt} \) represents the rate of change of the population size over time.
- \( n \) is the current number of individuals in the population.
- \( r \) is the intrinsic growth rate of the population.

3. **Components of the Formula:**
- **\( \frac{dn}{dt} \)**: This term indicates how quickly the population size is changing at a given moment.
- **\( n \)**: This is the existing number of individuals in the population at that time.
- **\( r \)**: This is the growth rate, which indicates how fast the population is growing per individual.

4. **Conclusion:**
- The correct answer to the question about the formula for exponential population growth is related to the growth rate, which is \( r \). Therefore, the answer is **growth rate**.
