What form of nitrogenous waste do most fishes excrete?
Most fishes primarily excrete ammonia as their nitrogenous waste. Ammonia is highly toxic but soluble in water, allowing it to be efficiently eliminated through the gills. This method is effective for aquatic animals since they have a constant supply of water to dilute the ammonia. Some species, especially those in saltwater environments, may also convert ammonia into less toxic compounds, such as urea, but ammonia remains the predominant form.
Nitrogenous waste that requires the least amount of water to excrete?
Uric acid is a nitrogenous waste that requires the least amount of water to excrete because it is mostly insoluble in water. This makes it advantageous for animals in dry environments or those with limited access to water. Examples of animals that excrete uric acid include birds and reptiles.
Why is the disposal of nitrogenous waste a problem for animals but not for plants?
The nitrates in nitrogenous waste reduce the oxygen carrying capabilities of the haemoglobin in the blood of animals. Since plants do not have haemoglobin they can absorb it to help them make proteins.
How do Pisces fish excrete waste?
Pisces fish excrete waste through their gills and kidneys. Waste products such as ammonia are released into the water through their gills, while the kidneys help filter out and excrete other waste materials.
What is the form of nitrogenous waste that most fish give off?
Most fish excrete nitrogenous waste in the form of ammonia. Ammonia is highly toxic, but fish eliminate it primarily through the gills and some through the urine. Some fish species, particularly those living in environments with low water availability, convert ammonia to a less toxic form, such as urea or uric acid, before excreting it.
How frogs dispose of nitrogenous waste?
Tadpoles excrete ammonia and frogs excrete urea

Why do humans excrete urea and not ammonia as your primary nitrogenous waste product?
They've lost the subsequent enzymes required for catalyzing the synthesis of urea into ammonia.
Why do marine fish excrete urine and why in fresh water excrete urea?
Neither marine nor freshwater fish excrete urine or urea; both marine and freshwater fish excrete nitrogenous waste products as pure ammonia.
What is ureotelic animals?
Animals that excrete in the form of urea nitrogenous waste derived from amino-acid catabolism
What is the excretory product of leeches?
Leeches primarily excrete waste in the form of ammonia, which is a common nitrogenous waste product in aquatic organisms. They use specialized structures called nephridia to filter and eliminate these waste products from their bodies. In addition to ammonia, leeches may also excrete other nitrogenous compounds depending on their environment and diet.
What 3 things can animals excrete?
Animals excrete a variety of substances through the excretory and respiratory systems. Three things they excrete are carbon dioxide, uric acid, and ammonia.
Do lungs excrete nitrogenous wastes?
The urinary system excretes nitrogenous wastes. The lungs excrete carbon dioxide.

Do swordfish excrete through their skin?
No, swordfish do not excrete through their skin. They primarily excrete waste through their kidneys and gills, similar to other fish. The kidneys filter waste products from the bloodstream, while the gills help eliminate ammonia and other nitrogenous wastes.
