A vegetarian food habits of man help in getting

Options

A. Less energy than non-vegetarian
B. More energy than non-vegetarian
C. Some amount of energy as in non-vegetarian
D. More or less same energy as non-vegetar-ian but depending upon the type of food taken.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks how vegetarian food habits of a man help in getting certain benefits or energy levels compared to non-vegetarian habits.

2. **Analyzing Energy Transfer**: In an ecosystem, energy is transferred through food chains. In a vegetarian diet, humans consume plants directly. In contrast, non-vegetarians consume animals that have eaten plants, creating a longer food chain.

3. **Energy Efficiency**: Energy transfer in food chains is not 100% efficient. Typically, only about 10% of the energy is passed from one trophic level to the next. Therefore, when a man eats a non-vegetarian diet, he receives less energy because it has been transferred through multiple levels (plant → animal → man).

4. **Comparing Energy Levels**: Since vegetarians consume plants directly, they receive more energy compared to non-vegetarians. This is because the energy is not lost in the intermediate step of consuming animals.

5. **Evaluating the Options**:
- **Option 1**: Less energy than non-vegetarian - This is incorrect because vegetarians receive more energy.
- **Option 2**: More energy than non-vegetarian - This is correct as explained above.
- **Option 3**: Some amount of energy as in non-vegetarian - This is misleading because while the energy might be similar depending on the type of food, the direct consumption of plants generally provides more energy.

6. **Conclusion**: The correct answer is that vegetarian food habits help in getting **more energy than non-vegetarian food habits** due to the direct consumption of plants.
