Explanation:

Moving from the Arctic to the tropics involves going from a cold - low precipitation region to a warm - high precipitation region. Biomes are determined by climate factors like temperature and precipitation. As one travels southward, both mean annual temperature and mean annual precipitation increase, leading to the observed change in vegetation.
