The correct Answer is:
To solve the question regarding the population dynamics of a given population of 2000 individuals with 80 births and 125 deaths, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Initial Population**: - The initial population is given as 2000 individuals. 2. **Calculate the Net Change in Population**: - To find the net change in population, we subtract the number of deaths from the number of births: \[ \text{Net Change} = \text{Births} - \text{Deaths} = 80 - 125 = -45 \] - This indicates that the population has decreased by 45 individuals. 3. **Determine the New Population Size**: - To find the new population size after accounting for births and deaths: \[ \text{New Population} = \text{Initial Population} + \text{Net Change} = 2000 - 45 = 1955 \] 4. **Analyze Population Trend**: - Since the number of deaths (125) is greater than the number of births (80), the overall trend indicates a decline in the population. 5. **Select the Appropriate Graph**: - Given the declining trend in population, we need to identify which graph among the options represents a declining population over time. - The correct graph will show a downward slope, indicating a decrease in population size. ### Conclusion: - After analyzing the options, the correct graph corresponds to a declining population, which is represented in **Option 1**.

To solve the question regarding the population dynamics of a given population of 2000 individuals with 80 births and 125 deaths, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Initial Population**: - The initial population is given as 2000 individuals. 2. **Calculate the Net Change in Population**: ...
