Population growth curve in most animals , except humans, is

Options

A. S - shaped
B. J - shaped
C. J - shaped with tail
D. S - shaped with tail

Answer

To solve the question regarding the population growth curve in most animals, except humans, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks about the shape of the population growth curve in most animals, excluding humans.

2. **Define Population Growth Curves**:
- **J-shaped Curve**: This curve represents exponential growth, where the population size increases rapidly without any limiting factors. It is characteristic of human population growth.
- **S-shaped Curve**: This curve represents logistic growth, where the population grows rapidly initially but then levels off as it approaches the carrying capacity of the environment.

3. **Analyze Human Population Growth**:
- The population growth curve for humans is typically J-shaped, indicating exponential growth due to advancements in medicine, technology, and agriculture.

4. **Analyze Population Growth in Other Animals**:
- In contrast, most animal populations exhibit an S-shaped curve, which reflects logistic growth. This is because their growth is often limited by environmental factors such as food availability, space, and predation.

5. **Conclusion**: Based on the analysis, the population growth curve in most animals, except humans, is S-shaped.

### Final Answer:
The population growth curve in most animals, except humans, is **S-shaped**.
