Terrestrial animals are generally either ureotelic or uricotelic, not ammonotelic, why?

Explanation

### Step-by-Step Solution:

1. **Understanding Excretion Types**:
- Terrestrial animals can be classified based on the type of nitrogenous waste they excrete: ammonotelic (excreting ammonia), ureotelic (excreting urea), and uricotelic (excreting uric acid).

2. **Characteristics of Ammonotelic Excretion**:
- Ammonotelic animals, such as many aquatic organisms, excrete ammonia directly into the water. Ammonia is highly toxic and requires a large amount of water to dilute it for safe excretion.
