The three choices are arctic tundra, tropical forest and desert

Throughout the world, regions with similar climates tend to have similar ecological communities, especially with respect to vegetation types. Based on these shared characteristics, all terrestrial regions can be categorized into several major biomes Specifically, ecologists typically classify biomes based on differences in long-term, average annual precipitation and temperature. For example, the chaparral biome has, on average, 10-20 cm (3-8 in) of precipitation per year, and its average temperatures can range from 2°C (36°F) to 23°C (73°F) throughout the year (as seen on the following graph). Examine the graph, which describes the general ranges of annual temperature and precipitation of eight biomes. Three biomes are missing labels; use the dropdown lists to correctly identify these biomes 35 30 U 25 20 15 10 Savanna Temperate deciduous forest 0 Boreal forest -10 -20 100 150 Mean annual precipitation (cm) 50 200 250 300

Explanation / Answer

Ans:

(1) Orange colour represents tropical forest, because mean annual precipitation and mean annual temperature both are very high.

(2) Brown colour represents desert, because mean annual precipitation is low but the mean annual temperature is high. Varies from 5°-30°c

(3) Pink colour represents tundra forest, because mean annual precipitation is very low and mean annual temperature is very low.
