Which type of forest is known for having rich biodiversity and high rainfall?

The tropical rainforest is recognized for its exceptionally rich biodiversity and abundant rainfall, making it one of the most vibrant ecosystems on the planet. These forests typically receive more than 100 inches of rainfall annually, which is crucial for sustaining the diverse array of plant and animal life. The warm, humid climate contributes to rapid decomposition and nutrient cycling, supporting a wide variety of species.

In contrast, the other types of forests mentioned do not share the same level of rainfall or biodiversity. Tundra, characterized by its cold climate, has limited biodiversity and is not known for lush plant life. Temperate forests, while biodiverse, do not compare to the sheer volume of species found in tropical rainforests. Deciduous forests can support diverse ecosystems but still fall short of the biodiversity levels seen in tropical rainforest environments. Thus, the environment of a tropical rainforest, with its unique climate and ecological characteristics, makes it the best answer to the question.
