Answer:
<em>d. Tundra</em>
Explanation:
Tundra <em>is a sort of biome in physical geography, where cold temperatures and short growing seasons hinder the growth of the plant.</em>
This consists of dwarf shrubs, sedges and grasses, mosses and lichens. In some tundra areas, scattered trees are growing.
The tundra-forest ecotone (or ecological boundary region) is called the tree line or timberline.
The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Normal warming is mostly caused by natural gases.
