Answer

To determine which of the following pairs is wrong, we need to analyze the terms related to nitrogenous waste elimination in different organisms.

### Step-by-Step Solution:

1. **Understanding Terms:**
- **Eurycotelic:** Refers to organisms that excrete uric acid as their nitrogenous waste. Common examples include birds and reptiles.
- **Ureotelic:** Refers to organisms that excrete urea as their nitrogenous waste. Mammals are a primary example.
- **Ammonotelic:** Refers to organisms that excrete ammonia as their nitrogenous waste. This is typical for aquatic animals, such as fish and tadpoles.

2. **Analyzing the Pairs:**
- **Eurycotelic with Birds:** This is correct as birds excrete uric acid.
- **Euryotelic with Insects:** This is incorrect because insects are uricotelic, not ureotelic. They excrete uric acid.
- **Ammonotelic with Tadpole:** This is correct as tadpoles excrete ammonia.
- **Euryotelic with Elephant:** This is correct as elephants are mammals and excrete urea.

3. **Identifying the Wrong Pair:**
- The pair that is incorrect is **Euryotelic with Insects** because insects are uricotelic, not ureotelic.

### Conclusion:
The wrong pair is **Euryotelic with Insects**.
