Answer

To answer the question regarding when the value of 'r' is significantly low compared to others, we need to understand the concept of 'r' in the context of population ecology.

### Step-by-Step Solution:

1. **Understanding 'r':**
- The letter 'r' represents the intrinsic rate of natural increase in a population. It is a measure of how quickly a population can grow under ideal conditions, without any limitations such as food shortages or predation.

2. **Low 'r' Value Implications:**
- When the value of 'r' is significantly low, it indicates that the population is not growing rapidly. This can occur due to various factors such as limited resources, high mortality rates, or environmental constraints.

3. **Population Dynamics:**
- In ecological terms, a low 'r' value suggests that the population is likely in a stable or declining phase rather than an exponential growth phase. This is often seen in populations that are at or near their carrying capacity.

4. **Terminology:**
- When 'r' is low, the population is often referred to as being in a "K-selected" strategy, where the focus is on maintaining a stable population size rather than rapid growth. K-selected species tend to have longer lifespans, fewer offspring, and invest more in parental care.

5. **Conclusion:**
- Therefore, when the value of 'r' is significantly low compared to others, it is better known as being characteristic of K-selected species or populations.

### Summary:
When 'r' is low, it indicates a stable population often associated with K-selected species, which focus on maintaining their population size rather than rapid growth.
