AP BIOLOGY

Detailed explanation-1: -A simple way to organize biomes is by their climate (temperature and precipitation).

Detailed explanation-2: -Because climate determines plant growth, it also influences the number and variety of other organisms in a terrestrial biome. Biodiversity generally increases from the poles to the equator. It is also usually greater in more humid climates.

Detailed explanation-3: -Biomes are described by their vegetation because plants that grow in an area determine the other organisms that can live there. Plants in a particular biome have characteristics, specialized structures, or adaptations that allow the plants to survive in that biome.

Detailed explanation-4: -The biome concept organizes large-scale ecological variation. 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).
