Explain how bioregional economics applies to greater resource productivity.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

not sure if this is what you'r looking for eubacteria and archaebacteria

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
