AP BIOLOGY

Detailed explanation-1: -Temperate forests are the most common biome in eastern North America, Western Europe, Eastern Asia, Chile, and New Zealand (Figure 9 below). This biome is found throughout mid-latitude regions.

Detailed explanation-2: -Tropical Forest Biomes Tropical forests are found in areas centered on the equator (Figure 4). Central and South America possess half of the world’s tropical forests. Climate in these biomes shows little seasonal variation (Figure 5), with high yearly rainfall and relatively constant, warm temperatures.

Detailed explanation-3: -The major desert biomes of the earth are found primarily at 30 degrees North and South latitude, in the interiors of continents. Climatically, deserts are influenced by descending air currents and have less than 25 millimeters of precipitation annually.

Detailed explanation-4: -Geographic Range: Temperate grasslands and shrublands occur in the middle latitudes (25-55°) of the northern and southern hemispheres.

Detailed explanation-5: -Tropical grasslands are found mainly in the Sahel south of the Sahara, in East Africa, and in Australia. Temperate grasslands principally occur in North America, Argentina, and across a broad band from Ukraine to China, but in most of these regions they have been substantially altered by agricultural activities.
