Reef Chemistry Question of the Day #71
Since today is Thanksgiving (in the US, at least), we'll pick an appropriate topic: eating.
As you sit down to your Thanksgiving dinner, your fish are watching you from the tank. You've had them all for many years, and are quite attached to them. Not only do they see you overeating, but you have them on a reduced food plan to try to deal with some green hair algae that is showing up in a few places.
Feeling guilty, you decide they should get a treat today, so you give them a little extra food. Nevertheless, they consume it all while you watch.
All quality foods contain substantial phosphate in the form of various biomolecules such as DNA, RNA, phospholipids, and proteins.
What fraction of the phosphate in the foods that they eat for Thanksgiving will most likely be released (by excretion or in fecal pellets) over the next few days?
A. Less than 10%
B. 10-30%
C. 30-60%
D. Greater than 60%
Good luck and have a nice Thanksgiving!
