Atoad is brought into a new ecosystem. it is stronger than the toads that already live there and reproduces quickly. which is the best way to describe these toads in the new ecosystem?

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."
