Consider the two biomes: tundra and desert. They are alike in some ways; different in others. The plants that live in both biomes have adaptations that allow them to live without much available water. There is one very important way the biomes differ. Because of this abiotic feature, plants in the turn are low growing and have silver-white hairs on the leaves to help absorb sunlight. What is this important difference between the two biomes?
