Detailed explanation-1: -Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.

Detailed explanation-2: -There are eight major terrestrial biomes: tropical rainforests, savannas, subtropical deserts, chaparral, temperate grasslands, temperate forests, boreal forests, and Arctic tundra. Biomes are large-scale environments that are distinguished by characteristic temperature ranges and amounts of precipitation.

Detailed explanation-3: -The distribution of biomes is determined by environmental conditions, which must be appropriate to support the dominant species. Moisture and temperature are usually the most important environmental influences on the distribution of terrestrial biomes (Figure 8.2).

Detailed explanation-4: -Altitude and latitude, which affect temperature and precipitation determine the distribution of biomes. Figure 8.1. a: Average annual temperature and annual precipitation are two climatic factors that determine the distribution of biomes.
