Final answer:
The tundra landscape supports the growth of small shrubs, mosses, and lichens.
Step-by-step explanation:
The tundra is a landscape where the top soil unfreezes during the summer, allowing for the growth of small shrubs, mosses, and lichens. This is because the soil is in a perennially frozen state, which inhibits the penetration of roots and slows down the decay of organic matter.
