We can’t recycle all of the proteins we eat, because some are wasted due to inefficiencies in metabolism, and some are lost through natural activities of daily living: sloughing of skin cells hair growth DNA/RNA breakdown undigested protein (eaten by bacteria in the colon) sweat urine ...
Ammonia is toxic to fish at high levels, so it needs to be efficiently removed from the water. In an aquaponics system, this waste is the starting point of the nutrient cycle that benefits the plants. 2. Bacteria Conversion of Ammonia to Nitrates (Nitrification Process) Beneficial bacteria ...
While many sources seem to indicate that sinking poops are preferred, others suggest that floaters are a sign that the diet contains a good amount of fiber. This is because those who eat more fiber, also known as prebiotics, have greater colonies of bacteria in the lower gut. This leads ...

The chlorine solution you pour into the water breaks down into many different chemicals, including hypochl...
H2O formula, which shows that hydrogen is the main building block of water, which is in turn the most common and important substance in the human body. This is the main role of hydrogen in supporting organisms: helping to create water, which animals, plants and humans need to survive. ...
