# Ecological Population Growth Study

An ecologist studies three populations within an ecosystem. Each population has an identical intrinsic growth rate ( \( r_{max} = 0.5 \) ). The population sizes and carrying capacities are shown in the graph below.

## Graph Analysis

### Description:
- **X-axis:** Represents the three populations, labeled A, B, and C.
- **Y-axis:** Represents the number of individuals in each population, ranging from 0 to 1000.
- **Legend:**
  - **Blue Bars:** Indicate the current population size.
  - **Red Bars:** Indicate the carrying capacity, which is the maximum population size that the environment can sustain.

### Data:
- **Population A:**
  - **Size:** Approximately 100 individuals.
  - **Carrying Capacity:** Approximately 200 individuals.
- **Population B:**
  - **Size:** Approximately 400 individuals.
  - **Carrying Capacity:** Approximately 500 individuals.
- **Population C:**
  - **Size:** Approximately 900 individuals.
  - **Carrying Capacity:** Approximately 1000 individuals.

## Question:
What is the growth rate of Population C? _____

### Graph Interpretation:
The graph shows the difference between the current population sizes and their respective carrying capacities. The intrinsic growth rate (\( r_{max} \)), set to 0.5, is a constant factor for all populations. To calculate the growth rate of Population C, we'll utilize the provided intrinsic growth rate along with the current population size and carrying capacity.

### Calculation:
To find the growth rate of Population C, the following formula can be used:
\[ \text{Growth Rate} = r_{max} \times \left(1 - \frac{\text{Population Size}}{\text{Carrying Capacity}}\right) \times \text{Population Size} \]

Substitute the values for Population C:
\[ \text{Growth Rate} = 0.5 \times \left(1 - \frac{900}{1000}\right) \times 900 \]

\[ \text{Growth Rate} = 0.5 \times (1 - 0.9) \times 900 \]

\[ \text{Growth Rate} = 0.5 \times 0.1 \times 900 \]

\[ \text{Growth Rate} = 0.5 \times 90 = 45 \]

Thus,
