In a population of a habitat in one year 200 births, 150 deaths, 200 emigrations and 150 immigrations have occurred. The density of population

Options

A. Increased
B. Decreased
C. Remains unchanged
D. Cannot be predicted

Answer

To find the density of the population in the given habitat, we need to analyze the changes in population size based on the provided data.

### Step-by-Step Solution:

1. **Identify the given values:**
- Births (B) = 200
- Deaths (D) = 150
- Emigration (E) = 200
- Immigration (I) = 150

2. **Calculate the net change in population:**
The formula to calculate the change in population size is:
\[ \text{Population Change} = (\text{Births} + \text{Immigration}) - (\text{Deaths} + \text{Emigration}) \]
Substituting the values:
\[ \text{Population Change} = (200 + 150) - (150 + 200) \]

3. **Perform the calculations:**
- Calculate the total births and immigration:
\[ 200 + 150 = 350 \]
- Calculate the total deaths and emigration:
\[ 150 + 200 = 350 \]
- Now, substitute these totals back into the population change formula:
\[ \text{Population Change} = 350 - 350 = 0 \]

4. **Determine the effect on population density:**
Since the population change is 0, it indicates that the population size remains unchanged. Therefore, the density of the population will also remain unchanged.

5. **Conclusion:**
The density of the population remains unchanged.

### Final Answer:
The density of the population remains unchanged.
