A dense forest rich in biodiversity, found typically in tropical areas with consistently heavy rainfall.

• A. Desert
• B. Rainforest
• C. Tundra
• D. Grassland

Answer: (B)

Biomes are defined by climate and the kinds of plants and animals they support. A tropical rainforest is the biome that is a densely packed forest with a huge variety of species and a climate that brings heavy rainfall almost every month. The description—dense forest, rich biodiversity, in tropical areas with consistently heavy rainfall—fits a rainforest because such warm, wet conditions support a tall, multi-layered canopy and an extraordinary number of species. Deserts have very little rainfall and sparse vegetation, tundra is cold with very short growing seasons and low biodiversity, and grasslands are dominated by grasses with fewer trees and not the same dense forest structure or level of species variety. So, the rainforest best matches the given description.
