that is the decay of plants, animals and excretory products...
nitrogen, oxygen and preoteins aren't produced after decay...the only possibility is mineral salts...and i think that is the decay product of plants...

it's diffusion...cuz the membrane is partially permeable so the blue ink can diffuse outside causing the 'pure water' to change in appearance...i.e change to blue!

Oops! My bad
Its B , As the amount of energy released is low so the energy remaining in the products is high
the chemical path way is different as all the reactions of anaerobic repiration are not same
Carbondioxide is produced sometimes (like in bread making ,not produced in muscles)

Co2 is excreted by lungs only
Urea & excess ions by kidney only
so it's D water is excreted by all of them
