Exponential growth occurs when there is -

Options

A. Asexual reproduction only
B. Sexual reproduction only
C. No inhibition from crowding
D. A fixed carrying capacity

Answer

### Step-by-Step Solution:

1. **Understanding Exponential Growth**: Exponential growth refers to a situation where the growth rate of a population is proportional to its current size. This means that as the population increases, the rate of growth also increases.

2. **Identifying Conditions for Exponential Growth**: For exponential growth to occur, certain conditions must be met:
- There must be ample resources available (such as food, space, and other necessities).
- There should be no significant limitations or inhibitions from crowding or competition among individuals in the population.

3. **Exclusion of Other Factors**:
- Asexual or sexual reproduction alone does not determine exponential growth. Both types of reproduction can occur under different growth conditions.
- A fixed carrying capacity implies that there are limitations on resources, which contradicts the concept of exponential growth.

4. **Conclusion**: Therefore, exponential growth occurs when there is no inhibition from crowding and no limitations on resources. This allows the population to grow rapidly without any constraints.

### Final Answer:
Exponential growth occurs when there is no inhibition from crowding and no limitation of resources.
