* Climate: Tropical rainforests are characterized by high temperatures and rainfall year-round. Tundras are extremely cold, dry, and have very short growing seasons.
* Vegetation: Tropical rainforests have lush, diverse vegetation with towering trees, while tundras have sparse, low-lying vegetation like mosses, lichens, and small shrubs.
* Animals: Tropical rainforests have a vast array of animal life, while tundras have a relatively limited number of species adapted to the harsh conditions.
Other biomes with contrasting features to tropical rainforests include:
* Desert: Very dry and hot, with sparse vegetation.
* Taiga (Boreal Forest): Cold and snowy with coniferous trees.
While the tundra is the most contrasting in terms of climate, other biomes offer different types of contrasts to the tropical rainforest.
