Maximum survival and reproductive capacity shown by a population under optimal environmental conditions is called:

Options

A. carrying capacity
B. natality
C. biotic potential
D. vitality

Answer

To solve the question regarding the maximum survival and reproductive capacity shown by a population under optimal environmental conditions, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- We need to identify what "maximum survival and reproductive capacity" means in the context of ecology and population biology.

2. **Identify the Options**:
- The options provided are:
a) Carrying capacity
b) Natality
c) Biotic potential
d) Vitality

3. **Analyze Each Option**:
- **Carrying Capacity**: This refers to the maximum number of individuals of a particular species that an environment can support sustainably. It is not specifically about maximum reproductive capacity under optimal conditions.
- **Natality**: This term refers to the birth rate of a population. While it relates to reproduction, it does not encompass the idea of maximum capacity under optimal conditions.
- **Biotic Potential**: This term describes the maximum reproductive capacity of an organism under optimal environmental conditions, meaning it reflects the highest possible growth rate of a population.
- **Vitality**: This term generally refers to the health and energy of an organism, not specifically related to reproductive capacity.

4. **Select the Correct Answer**:
- Based on the analysis, the correct answer is **Biotic Potential** (Option c), as it directly refers to the maximum survival and reproductive capacity of a population under ideal conditions.

### Final Answer:
The maximum survival and reproductive capacity shown by a population under optimal environmental conditions is called **Biotic Potential**.
