What type of ecosystem is characterized by evergreen coniferous forests and a slightly warmer climate than tundra?

The type of ecosystem characterized by evergreen coniferous forests and a slightly warmer climate than tundra is the taiga. This biome, also known as boreal forest, is found in high-latitude regions where the climate is generally cooler, but not as extreme as that found in tundra ecosystems. Taiga features trees that are adapted to cold temperatures, such as spruce, fir, and pine, which thrive in its slightly milder conditions compared to the harsh tundra, where tree growth is severely limited due to permafrost and a shorter growing season.

In contrast, the desert is characterized by arid conditions and sparse vegetation, while grasslands exhibit a mix of grasses and few trees, thriving in more temperate climates. The tundra, while it shares some polar characteristics with the taiga, is devoid of trees and instead has limited vegetation primarily consisting of mosses and lichens due to its colder temperatures and shorter growing periods. The presence of coniferous forests makes taiga distinct from these other ecosystems, further solidifying its classification.
