Population size more technically called ………..A……..(designated as N ) need not necessarlity to be measured in …….B……..only
Choose the correct option for A and B

Options

A. A-population natality , B-numbers
B. A-population mortality , B-numbers
C. A-population density ,B-numbers
D. A-population density ,B-pyramid

Answer

To solve the question, we need to identify the correct terms for A and B in the statement provided.

### Step-by-Step Solution:

1. **Understanding Population Size**:
- The question refers to "population size," which is a fundamental concept in ecology. Population size indicates the number of individuals in a given population.

2. **Identifying Term A**:
- The video transcript mentions that population size is technically referred to as "population density." Population density is defined as the number of individuals per unit area.
- Therefore, for term A, the correct answer is **population density**.

3. **Identifying Term B**:
- The transcript explains that population density (N) does not have to be measured solely in numbers. It can also be represented in other forms, such as percentages or through methods like the quadrate method.
- Thus, for term B, the correct answer is **numbers**.

4. **Final Answer**:
- A = population density
- B = numbers

### Conclusion:
The correct completion of the statement is: "Population size more technically called **population density** (designated as N) need not necessarily to be measured in **numbers** only."
