If in a population, natality is balanced by mortality, then there will be

Options

A. increase in population growth
B. decrease in population growth
C. zero population growth
D. over population

Answer

To solve the question, "If in a population, natality is balanced by mortality, then there will be," we can follow these steps:

### Step-by-Step Solution:

1. **Define Natality and Mortality**:
- Natality refers to the birth rate of a population, indicating how many individuals are born in a given time period.
- Mortality refers to the death rate, indicating how many individuals die in the same time period.

2. **Understand the Relationship**:
- When natality (birth rate) is equal to mortality (death rate), it means that the number of individuals being born is equal to the number of individuals dying.

3. **Identify the Implication**:
- If natality balances mortality, the overall population size remains stable over time. This means there is no net increase or decrease in the population.

4. **Define the State of the Population**:
- This condition is referred to as a "transition state" or "zero population growth." In this state, the population neither grows nor shrinks.

5. **Evaluate the Options**:
- Based on the understanding that there is no change in population size, we can conclude that the correct answer to the question is that there will be zero population growth.

### Final Answer:
If in a population, natality is balanced by mortality, then there will be **zero population growth**.
