An ecosystem dominated by lichens, mosses, grasses, and woody plants. it is generally found at high latitudes. it is described as having a marshy surface where mosses, lichens, berries and low shrubs grow with mucky soil and permafrost underneath. what is this ?

Tundra

Explanation:

Tundra is a type of biome characterized by low temperature and short growth season and generally found at high latitudes. The soil is solid, frozen and known as permafrost. It forms when the temperature is below -5° celsius. Tree roots are not able to penetrate this frozen soil so only shrubs, grasses, moss and lichens can grow here. Hence, tundra climate is hostile to woody vegetation. In summers when the top layer of permafrost melts, it leaves behind marshy and soggy grounds and bogs. There are three types of tundra: arctic, antarctic and alpine.
