Options

A. 0.08 off spring per lotus per year
B. 0.02 off spring per lotus per year
C. 0.04 of spring per lotus per year
D. 0.06 off spring per lotus per year

Answer

To solve the problem of calculating the birth rate of lotus plants in the pond, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Original Population**:
The original population of lotus plants in the pond is given as 201.

2. **Identify the Change in Population**:
The problem states that 8 new lotus plants are added through reproduction. Therefore, the change in population is 8.

3. **Calculate the Birth Rate**:
The birth rate can be calculated using the formula:
\[ \text{Birth Rate} = \frac{\text{Change in Population}}{\text{Original Population}} \]
Substituting the values we have:
\[ \text{Birth Rate} = \frac{8}{201} \]

4. **Perform the Division**:
Now we perform the division:
\[ \frac{8}{201} \approx 0.0398 \]

5. **Round the Result**:
Rounding 0.0398 to two decimal places gives us approximately 0.04.

6. **Final Answer**:
Therefore, the birth rate of the lotus plants in the pond is approximately 0.04 offspring per lotus plant per year.
