A. Population grows in an exponential or geometric fashion
B. Impact of natality and mortality becomes zero
C. Biotic potential will be minimum
D. Population always shown Verhulst pearl-logistic growth

Answer

To solve the question "When resources in the habitat are unlimited?", we will analyze the implications of unlimited resources on population dynamics.

### Step-by-Step Solution:

1. **Understanding Unlimited Resources**:
- When resources in a habitat are unlimited, organisms have access to all the necessary resources for survival, reproduction, and growth. This includes food, space, and other essential factors.

**Hint**: Think about what happens when there are no limitations on resources for a population.

2. **Population Growth**:
- In such a scenario, the population can grow without restrictions. This type of growth is referred to as exponential or geometric growth. The population will increase rapidly as each individual can reproduce freely without competition for resources.

**Hint**: Consider how the absence of limiting factors affects the reproduction rates of organisms.

3. **Evaluating Options**:
- **Option 1**: "Population grows in an exponential or geometric fashion."
- This statement is correct. With unlimited resources, the population can grow exponentially.

- **Option 2**: "Impact of Natality and Mortality becomes zero."
- This statement is incorrect. Natality (birth rate) and mortality (death rate) will still exist, but the birth rate will far exceed the death rate due to the abundance of resources.

- **Option 3**: "Biotic potential will be minimum."
- This statement is also incorrect. Biotic potential refers to the maximum reproductive capacity of an organism under optimal environmental conditions. With unlimited resources, biotic potential would be maximized, not minimized.

- **Option 4**: "Population always shows logistic growth."
- This statement is incorrect. Logistic growth occurs when resources are limited, leading to a carrying capacity. Unlimited resources lead to exponential growth instead.

4. **Conclusion**:
- The correct answer is **Option 1**: "Population grows in an exponential or geometric fashion." This reflects the reality of population dynamics when resources are abundant.

### Summary:
When resources in a habitat are unlimited, the population grows exponentially due to the lack of limiting factors. Other options provided do not accurately represent the effects of unlimited resources on population dynamics.
