Detailed explanation-1: -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-2: -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: -Types of Terrestrial Biomes When warm and wet, tropical forests are called rainforests, while dry and cool conditions result in deciduous forests. They are characterized by thick canopy and tall or short trees. Temperate forests are found in regions that have mid-range temperatures and all four seasons.

Detailed explanation-4: -Altitude and latitude, which affect temperature and precipitation determine the distribution of biomes. Figure 22.2. 1: Average annual temperature and annual precipitation are two climatic factors that determine the distribution of biomes.

Detailed explanation-5: -Terrestrial biomes include all the land areas on Earth where organisms live. The distinguishing features of terrestrial biomes are determined mainly by climate. For example, in arid climates, plants may have special tissues for storing water. Biodiversity generally increases from the poles to the equator.
