Which Biome has high temperatures during the day and much cooler temperatures at night?
A
Tundra
B
Desert
C
Grasslands
D
Tropical Rain forest
Explanation: 

Detailed explanation-1: -The correct response is desert. The desert environment is characterized by low rainfalls (less than 25 cm per year). They are one of the most dry biomes on the planet. The desert biome also has highly variable temperature swings, with high temperatures during the day and low temperatures at night.

Detailed explanation-2: -Desert surfaces receive a little more than twice the solar radiation received by humid regions and lose almost twice as much heat at night. Many mean annual temperatures range from 20-25 degrees Celsius. The extreme maximum ranges from 43.5-49 degrees Celsius. Minimum temperatures sometimes drop to-18 degrees Celsius.

Detailed explanation-3: -The desert biome is a dry, terrestrial biome. It consists of habitats that receive very little rainfall each year, generally less than 50 centimeters. The desert biome covers about one-fifth of the Earth’s surface and includes regions at a variety of latitudes and elevations.

Detailed explanation-4: -Although some deserts are very hot, with daytime temperatures as high as 54°C (130°F), other deserts have cold winters or are cold year-round. And most deserts, far from being empty and lifeless, are home to a variety of plants, animals, and other organisms.

Detailed explanation-5: -Due to a lack of humidity in deserts, the air cannot hold the heat radiated by the sand, which gets heated during the sunny daytime hours. This causes the temperature of deserts to fall rapidly at night.
