Firstly, animals' cells need a small margine of 'salts' in their bodys to ensure enzymes and molecules can function efficiently, and to regulate pH of body fluids. Animals rely largely on their excretory organs (Liver & Kidneys) to remove waste and toxins, as well as control pH, ion concentrations and water balance.
Animals consume protein for energy and this contains nitrogen which is toxic to their systems. Nitrogenous waste first breaks down into ammonia, which is then converted to either urea or uric acid. Ammonia is toxic and it takes considerable energy to convert it into urea (which is less toxic) so usually, ammonia is only excreted by aquatic animals because it is diluted easily in their environment. Birds and reptiles excrete mostly uric acid, whereas mammals excrete their nitrogenous waste in the form of urea as their kidneys minimise water loss;an adaptation to living on land. The less water available, the more concentrated the waste.
Other adaptations to maintain water balance, although more 'behavioral', are seen in desert dwelling animals, e.g: Some have skin which absorbs rain and dew, some live under ground where the temperature is lower and has a higher water saturation content. Others do not drink, pant or sweat, and Kangaroo rats have learnt to collect dry grains at night, which absorb the water in the air in their burrows, thus enabling them to obtain this water when they eat.
What else can I help you with?
When do animals lose nitrogen?
Animals will lose nitrogen when they die. This is whey decay and nitrogen is released as ammonia into the air.
How do animals loose water?
Urination, defecation (there is some water in stools), skin loss (sweat), and exhalation loss (there is water in exhaled breath). Desert animals, such as camels, can cut these losses significantly. For menstruating females, add the water content of the expelled blood. For those with asthma or colds, add nasal loss.
What are the names of animals that live in water?

How do animals without sweat glances lose weight?

What three ways do animals lose water?
Animals lose water when they urinate, perspire, and exhale.
How do animals loose water from their bodies?
Animals lose water when they urinate, perspire, and exhale.
Animals lose water when they what?
Animals lose water when they breathe, urinate, defecate, and sweat. This water loss must be replenished through drinking water and eating moist foods to maintain proper hydration and normal physiological functions.
What are some ways plants and animals lose water?
Plants lose water through the process of evaporation. Animals, on the other hand, lose water through urination, defecation, and perspiration.
Why are desert animals mostly nocturnal?
In hot deserts it's cooler at night, so if animals come out then they lose less water.
How do animals lose energy?
Animals lose energy simply by existing. The more strenuous the activity they are performing, the more energy they will lose.
