The approximate weight of grains used to produce 1kg of meat by animal farming is

Options

A. 3-10 kg
B. 30-100 kg
C. 0.3-1.0 kg
D. 27-297 kg

Answer

To determine the approximate weight of grains used to produce 1 kg of meat by animal farming, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Relationship**: Recognize that animal farming requires a significant amount of grains to produce meat. The process of converting grains into meat is not efficient, and a large quantity of grains is needed to yield a smaller quantity of meat.

2. **Identifying the Range of Grains**: The options provided for the weight of grains used to produce 1 kg of meat are:
- 3 to 10 kg
- 30 to 100 kg
- 0.3 to 1 kg
- 27 to 297 kg

3. **Analyzing the Options**:
- The option "0.3 to 1 kg" seems too low because it implies a very efficient conversion which is not typical in animal farming.
- The option "30 to 100 kg" appears excessively high for the production of just 1 kg of meat.
- The option "27 to 297 kg" is also too high and unrealistic for standard farming practices.

4. **Selecting the Most Reasonable Option**: The most reasonable and commonly accepted range for the amount of grains required to produce 1 kg of meat is "3 to 10 kg." This range reflects the typical feed conversion ratio in animal farming, where it takes several kilograms of feed to produce a single kilogram of meat.

5. **Conclusion**: Therefore, the approximate weight of grains used to produce 1 kg of meat by animal farming is **3 to 10 kg**.

### Final Answer:
**3 to 10 kg**
