Pick 2 biomes, one with high rainfall and one with low rainfall. First, how much rainfall per year do they each get? Second, name 2 adaptations of organisms that live in this biome that reflect how much rainfall the biome receives.
What is "e.g. desert: low rainfall (<25cm/yr), not much vegetation, plants are especially adapted to dry conditions (succulents) and animals are most active at night when it's cooler; rainforest: >300cm/yr, lots of vegetation so there are understory plants that grow well in the shade, and tall trees that can reach the light above the other plants"
