Erosion is more likely to increase when the amount of vegetation decreases. The potential for soil erosion increases if the soil has no or very little vegetative cover of plants.
Plants and their residue form a cover that protects the soil from direct raindrop impact and splash, tending to slow down movement of runoff water and allows excess surface water to infiltrate, preventing erosion by water.
Plants root systems tend also to anchor top soil in place such that it is firm and cannot be easily blown away by wind thus preventing erosion by wind.
By definition, an arthropod is an animal that is invertebrate and has an exoskeleton also known as an external skeleton. In addition they have a jointed appendages. Other characteristics include segmented bodies, open circulatory systems and bilateral symmetry. Based on this we can say that from the list given we can select "endoskeleton" "jointed appendages"
