The amount of variation in living organisms is called biodiversity. The Alpine biome has a low biodiversity and relatively low population numbers at higher trophic levels. Why do you think this is? (*Hint:
what's a limiting factor here?).

we would need to see the picture to answer it

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."
