Pattern of population results in a J-shaped curve obtained in

Options

A. logistic growth
B. exponential growth
C. sigmoid growth
D. all of these

Answer

**Step-by-Step Solution:**

1. **Understanding Population Growth Patterns:**
- Population growth can be represented in different patterns, primarily exponential and logistic growth.
- Exponential growth occurs when resources are unlimited, leading to a rapid increase in population size.

2. **Identifying the J-shaped Curve:**
- The J-shaped curve represents exponential growth. This curve indicates that as the population increases, it does so at an accelerating rate, forming a shape similar to the letter "J".

3. **Contrast with Logistic Growth:**
- In contrast, logistic growth is represented by an S-shaped curve (sigmoid growth). This type of growth considers the carrying capacity of the environment, meaning that resources are limited and the population growth will eventually slow down as it approaches this limit.

4. **Defining Carrying Capacity:**
- Carrying capacity (denoted as K) is the maximum population size that an environment can sustain indefinitely without being degraded. Beyond this capacity, the resources become insufficient to support the population.

5. **Conclusion:**
- Since the question specifically asks for the pattern of population that results in a J-shaped curve, the correct answer is **exponential growth**.

**Final Answer:**
The pattern of population that results in a J-shaped curve is **exponential growth**.
