AP BIOLOGY

Detailed explanation-1: -Moving from the poles to the equator, you will find (in order) Arctic, boreal, temperate, subtropical, and tropical biomes.

Detailed explanation-2: -Why do the same biomes occur at similar latitudes and around the globe? The same biomes occur at similar latitudes because of the north south temperature gradient in temperature and atmospheric circulation patterns.

Detailed explanation-3: -As latitude and altitude increase, biomes and vegetation change. Trees of tropical rainforests usually grow closer to the equator, while mosses and lichen of the tundra grow closer to the poles.

Detailed explanation-4: -Biomes are determined primarily by temperature and precipitation. Generally speaking, biomes at higher latitudes (further away from the equator) are cooler and drier. Closer to the equator, biomes are generally warmer and wetter, as warmer air holds more moisture than colder air.
