Answer:
The tree will not survive due to the nature of the tundra
Explanation:
The tundra comes from a finnish word "tunturia" which means barren or treeless land. It is classified as a cold icy desert with permafrost on the ground. Unlike the tropical rain forest which is a wet climate group and is a forest of tall trees in a region of year round warmth, the tundra is cold and dry. The tundra soils are formed at high altitudes, they are usually frozen. Common plants in tundra are shrubs, herbs, lichens and grass and usually grow in groups and remain closer to the ground for prevention against cold winds. The cold nature of the tundra and its soil prevent the growth of trees because trees need to have deeper roots and they cannot grow on frozen ground.
