AP BIOLOGY

Detailed explanation-1: -Explanation: The primary factor which determines a biome is the climate. Temperature and precipitation essentially determines what kind of growing season or soil quality the terrain may have, which therefore affects the growth of plants living there.

Detailed explanation-2: -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).

Detailed explanation-3: -Precipitation. Rainforests receive the most rain of all of the biomes in a year! A typical year sees 2, 000 to 10, 000 millimeters (79 to 394 inches) of rain per year.

Detailed explanation-4: -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-5: -biome, also called major life zone, the largest geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions. It includes various communities and is named for the dominant type of vegetation, such as grassland or coniferous forest.
