Ammonotelism is a form of nitrogen waste excretion primarily found in aquatic animals, where ammonia is directly excreted into the surrounding water due to its high solubility and toxicity. This process is energy-efficient but requires a large amount of water to safely dilute the ammonia, making it unsuitable for terrestrial animals with limited water access.
When you put paper in water, it gets wet and can become soggy and break apart. This happens because paper is made of tiny fibers that soak up water, making it weak and easy to tear.
