The physiological capacity of a species to produce their progeny in absence of predators, diseases and other inhibiting factors is called:

Options

A. carrying capacity
B. biotic potential
C. environmental resistance
D. population explosion

Explanation

To solve the question regarding the physiological capacity of a species to produce their progeny in the absence of predators, diseases, and other inhibiting factors, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the term that describes the ability of a species to reproduce under ideal conditions, free from threats like predators and diseases.

2. **Analyze the Options**: The options provided are:
- A) Carrying capacity
- B) Biotic potential
- C) Environmental resistance
- D) Population explosion

3. **Define Each Term**:
- **Carrying Capacity**: This refers to the maximum number of individuals of a species that an environment can sustain indefinitely without degrading the environment.
- **Biotic Potential**: This is the maximum reproductive capacity of an organism under optimal environmental conditions, where there are no limiting factors.
- **Environmental Resistance**: This encompasses all the factors that limit the growth of a population, including predators, diseases, and food scarcity.
- **Population Explosion**: This refers to a rapid increase in the number of individuals in a population, often following a period of low population density.

4. **Identify the Correct Term**: Given the definitions, the term that best describes the physiological capacity of a species to produce progeny in the absence of inhibiting factors is **Biotic Potential**. This term specifically refers to the reproductive capacity when conditions are ideal.

5. **Conclusion**: Therefore, the correct answer to the question is **B) Biotic potential**.
