just tried to reset my password and got stuck on the "what substance is found in a swale" so i thought ditch or bunding running parallel to contour lines to slow water run off allowing better penetration of rainfall and reducing errosion - which means it might contain soil/earth/dirt/clay/sand/gravel on the downhill side and air or water on the uphill side depending on the weather - but none of these answers was correct, so i was wondering what is the proper answer?
The photosynthesis question was a bit bad as it the process produces sugar for cell growth (and O2) not biomass directly.
TG for the worms!
