Which of the following are the main source of carbohydrates

Options

A. Green plant
B. Fructose
C. Glucose
D. Both (b) and (c)

Answer

To determine the main sources of carbohydrates, we can analyze the options provided in the question. Here’s a step-by-step solution:

### Step 1: Identify the options
The options given are:
1. Green Plants
2. Prectose
3. Glucose
4. Both B and C

### Step 2: Understand the role of Green Plants
Green plants are known to be the primary producers in ecosystems. They perform photosynthesis, a process that converts sunlight, carbon dioxide, and water into glucose and oxygen. The glucose produced is a simple carbohydrate and serves as a fundamental energy source for plants and, subsequently, for animals that consume them.

### Step 3: Analyze other options
- **Prectose**: This term seems to be a misspelling or confusion with "fructose" or "dextrose." However, it is not a primary source of carbohydrates itself but rather a type of sugar.
- **Glucose**: While glucose is a simple sugar and a direct product of photosynthesis, it is not a source of carbohydrates in the way that plants are. It is more of a product derived from carbohydrates.
- **Both B and C**: This option suggests that both Prectose and Glucose are sources of carbohydrates, which is misleading as they are not primary sources.

### Step 4: Conclusion
Based on the analysis, the main source of carbohydrates is indeed **Green Plants**. They produce various carbohydrates, including cellulose, starch, and sugars, which are essential for the food chain.

### Final Answer:
The main source of carbohydrates is **Green Plants** (Option 1).
