Gas Cam

Every living thing respires, all day and all night. Plants also photosynthesise, but only in the light. Film a nature show round Lemon Marsh from noon to sunrise and snap the shots the director asks for: who is taking in carbon dioxide, who is giving it out, and who has no net gas exchange. Stuck? Switch on Indicator Vision to see everything in hydrogen-carbonate indicator colours.
