AP BIOLOGY

Detailed explanation-1: -A. TUNDRA: treeless low (less than 1 m) vegetation with short perennials, water frozen.

Detailed explanation-2: -Savanna is grassland with scattered individual trees. Savannas of one sort or another cover almost half the surface of Africa (about five million square miles, generally central Africa) and large areas of Australia, South America, and India. Climate is the most important factor in creating a savanna.

Detailed explanation-3: -Terrestrial biomes are distinguished primarily by their predominant vegetation, and are mainly determined by temperature and rainfall. Differences in temperature or precipitation determine the types of plants that grow in a given area (Figure 1).

Detailed explanation-4: -The temperate forest biome and savanna biome are the two biomes which have predominantly deciduous vegetation. Temperate forests have low winter temperatures and high levels of rainfall while savannas have long dry seasons and high temperatures.
