Question

which biome experiences the largest temperature swings between day and night? desert tropical rainforest grassland taiga

Explanation:

Deserts have sparse vegetation and little water. During the day, the sun heats the ground rapidly as there's no canopy or much moisture to retain heat evenly. At night, with no insulation from vegetation or water vapor, heat escapes quickly into the atmosphere. Tropical rainforests have dense canopy and high humidity that moderate temperature. Grasslands have some vegetation and more moisture than deserts. Taiga (boreal forest) has trees and more consistent moisture - temperature regulation compared to deserts.

Answer:

Desert
