Solution
The correct option is B Savannah
Tundra is the coldest of all the biomes. It is noted for its extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. The tropical rain forest is a forest of tall trees in a region of year-round warmth. The temperature in a rain forest rarely gets higher than 34 C or drops below 20 C; rainfall is often more than 100 inches a year. There is usually a brief season of less rain. Grasses are the dominant vegetation in temperate grassland. Temperate grasslands have hot summers and cold winters. Summer temperatures can be over 100 degrees Fahrenheit, while winter temperatures can be as low as -40 degrees Fahrenheit. They have between 10 and 35 inches of precipitation a year, occurring in the late spring and early summer. A savannah is a grassland ecosystem characterized by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Savannah has distinct wet and dry seasons of relatively equal duration. Most of the region's annual rainfall is experienced during the wet season and very little precipitation falls during the dry season. Savannah climates have monthly mean temperatures above 18 C (64 F) in every month of the year.Therefore, the correct answer is option B.
