Question

which low - rainfall biome is experiencing the most desertification due to climate change and increased temperatures? grasslands tropical rainforests deciduous forests temperate rainforests

Explanation:

Grasslands are low - rainfall biomes. Climate change leads to increased temperatures and reduced precipitation. In grasslands, these factors (along with over - grazing, poor agricultural practices in some cases) contribute to desertification. Tropical rainforests have high rainfall, and deciduous forests (while they can have seasonal changes in precipitation) are not typically low - rainfall biomes in the context of this question. Temperate rainforests also have relatively high rainfall.

Answer:

grasslands
