    Mass flow is the flow of sugar from the source to the sink down a pressure gradient

    There are lots of mass transport systems if I'm not wrong. Transportation of sucrose is one, the circulatory system is one and so is gas exchange.

    So for percentage change you want (final value-original value)/original value

    We have a drop from 4.2 to 0.8, so 4.2 is our original and 0.8 is our final value. If you put these into a calculator (0.8-4.2)/4.2= -0.809. Multiply by 100 and you get -80.9% which rounds to -81%. You don't need to include the minus as the question states that it's a decrease anyway.
