When resources are limited, populations exhibit logistic growth, In iongistic growth, population expansion decreases as resources become scarce, levilling off when the carrying capcity of the enviornment is reached, resulting in a ________curve.

Options

A. S-shaped
B. J - shaped
C. Straight line
D. Circular.

Answer

To solve the question regarding logistic growth and its representation on a graph, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Logistic Growth**:
- Logistic growth occurs when resources are limited. In such scenarios, the population growth rate decreases as the population reaches the carrying capacity of the environment.

2. **Identifying the Growth Curve**:
- The question asks for the type of curve that represents logistic growth. The key characteristics of logistic growth include an initial phase of slow growth, followed by a period of rapid growth, and finally leveling off as the population reaches the carrying capacity.

3. **Graph Representation**:
- To visualize this, we can plot a graph with the x-axis representing time and the y-axis representing population density.
- Initially, the population grows slowly (lag phase), then experiences rapid growth (log phase), and finally stabilizes (stationary phase).

4. **Shape of the Curve**:
- The resulting graph from this growth pattern will resemble an "S" shape. This is because the population starts off slowly, accelerates as resources are utilized, and then levels off as it approaches the maximum capacity of the environment.

5. **Conclusion**:
- Therefore, the correct answer to fill in the blank in the question is "S-shaped curve".

### Final Answer:
The resulting curve is an **S-shaped curve**.
