Why is biodiversity so high in tropical rainforest yet so low in tundra and desert biome?

Explanation:

In the tundra and desert, the land is mostly barren and has only a few species of plants and animals for organisms to feed on. In the tropical rainforest, it has lots of rain and more plants can grow, and that results in more herbavores to feed on the plants and more predators to feed on the herbavores.

Hope this helped!

Explanation:

biodiversity is high because the warm and wet consistent climate in tropical rainforests is as to sustain life in all different forms soul nutrient is poor in tropical rainforests because the sunlight that is intended to reach the floor of the tropical Forest is blocked by the tall and dense trees
