1. Because I live in water, I excrete urea, a water soluble nitrogenous waste.

Which of these animals correctly describe how its nitrogenous waste is related to its phylogeny and habitat?. 1. Because I live in water, I excrete urea, a water soluble nitrogenous waste. 3. Living on land, I need to conserve as much water as possible, so I excrete a solid nitrogenous waste.
