At the end of the school year, students in the science club cleaned up dead plants from the school garden and placed them in the school's two compost bins. Red worms were added to one bin but not the other bin. In the fall, the students notice that the bin with the red worms seems to have much less volume of material than the other bin. The best explanation for the decrease in volume is - 13 A red worms help plant matter decompose faster B during the summer, one bin was cleaned out C more sunlight fell on one bin than on the other bin D one bin received more moisture than the other
