through fish and human waste
Ammonia comes from fish waste.
Ammonia can be built up in them separately or the two together. Some species of fish produce more waste and therefore more ammonia than others, for example the goldfish. Turtles are also very wast producing and turtle tanks are often high in ammonia. All fish produce ammonia. So yes.

The same way a human does. by digesting food. :)
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.
Ammonia can be found in people also over 10,000,000 people have it in them and die from it
Cod fish or any type of fish will have ammonia like smell when it is no longer fresh. This smell will begin to appear as you are cooking it. It may also have a taste that is similar to ammonia, too.
Oh, yes. In pretty much the normal fashion. A little string comes out of the back of the fish. Almost all animals excrete wastes. Fishes excrete an ammonia-based waste product.
Fish poop is the common name for fish feces. If you are referring to dead fish parts which are not directly used in food, then fish waste is the proper term.
Just as we put out bi products when we breath so do fish. They also poo and wee in their environment. These products of life become deadly poisonous Ammonia as they break down. In order for things like fish and plants to be able to live, Nature developed specific bacteria to change the deadly poisonous Ammonia into relatively harmless Nitrate in water. Then the nitrate can be used up as food for water plants and algae. A "cycled" filter is simply a filter that has been running for long enough to develop the natural bacteria that converts Ammonia into Nitrate. The over abundance of Nitrate can be removed by simply doing a weekly water change.
A fish actually excretes ammonia dissolved in water. At the temperature and pressure that fish are normally found ammonia is a gas.
