In phse population adopt itself to new environment and starts to increase reproductive rate

Options

A. log phase
B. lag phase
C. decline phase
D. stationary phase

Answer

To answer the question about which phase a population adopts itself to a new environment and starts to increase its reproductive rate, we can break down the solution step by step.

### Step-by-Step Solution:

1. **Understanding Population Growth Phases**:
- In population ecology, there are different phases of population growth. The main phases are lag phase, log phase (or exponential phase), stationary phase, and decline phase.

2. **Identifying the Lag Phase**:
- The lag phase is the initial phase when a population is introduced to a new environment. During this phase, the population is adapting to the new conditions. The growth rate is slow because individuals are acclimatizing to their surroundings.

3. **Transition to Log Phase**:
- After the lag phase, once the population has adapted, it enters the log phase. In this phase, the reproductive rate increases significantly as the population begins to grow rapidly. This is characterized by exponential growth.

4. **Understanding Resource Limitations**:
- The logistic growth model indicates that as the population grows, it will eventually face limitations due to resources (like food and space). This leads to the next phases: stationary and decline phases.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the population adopts itself to the new environment during the **lag phase** and starts to increase its reproductive rate during the **log phase**.

### Final Answer:
The population adopts itself to the new environment during the **lag phase** and starts to increase its reproductive rate during the **log phase**.
