¿cómo se relacionan los seres vivos en un ecosistema?

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."

instead of copying and pasting things off of tests or work done on computer which im sure you did, try and read over the question carefully
