In which of the following alimentary canal,"starch glycogen" is produced ?

Options

A. Producer
B. 1st trophic level
C. 2nd trophic level
D. All the above

Answer

To solve the question "In which of the following alimentary canals is starch glycogen produced?", we will analyze the options provided and understand the role of each level in the food chain.

### Step-by-Step Solution:

1. **Understanding Starch and Glycogen**:
- Starch and glycogen are both polysaccharides that serve as storage forms of glucose in organisms. Starch is primarily found in plants, while glycogen is found in animals.

2. **Identifying the Options**:
- Option 1: Producers
- Option 2: First trophic level
- Option 3: Second trophic level
- Option 4: All of the above

3. **Analyzing Option 1 - Producers**:
- Producers, such as green plants, synthesize starch through photosynthesis. They store energy in the form of starch, but they do not produce glycogen.

4. **Analyzing Option 2 - First Trophic Level**:
- The first trophic level consists of herbivores that consume plants (the producers). These herbivores can convert the starch they consume into glycogen for storage. Therefore, starch glycogen is indeed produced at this level.

5. **Analyzing Option 3 - Second Trophic Level**:
- The second trophic level consists of carnivores or omnivores that eat herbivores. They do not produce starch or glycogen; instead, they utilize the glycogen stored in the herbivores they consume.

6. **Analyzing Option 4 - All of the Above**:
- Since not all options are correct, this option cannot be the answer.

7. **Conclusion**:
- The correct answer is **Option 2: First Trophic Level**, as it is here that starch glycogen is produced by herbivores that consume starch from plants.

### Final Answer:
**The starch glycogen is produced in the First Trophic Level.**
