2, the jungle tin preoccupy disadvantageous substances: sulfur dioxide, hydrogen fluoride.
produce courseware: a explicit sulfur dioxide namely a colorless gas, One of the chief pollutants in the atmosphere. volcanic outbreak ambition ooze the gas. fluoride is a colorless gas, will produce the scent stimuli.
3, the forest can secrete spinosad ......< br> 4, Forest The absorption of dust can ......< br> Division camera blackboard.
Teacher: praise your team, organized a very clear, very muscular language capabilities, for the group said they did not add the content?
Health added namely the camera to produce courseware for teachers: broad-leaved forest hectares a year 68 tons of dust, dust absorption delay.
