Both the taiga and the tundra are colder environments often found far north. How are the two biomes different?
A
The taiga is dominated by conifers and the tundra is dominated by grasses and sedges.
B
The taiga is a very dry climate and the tundra is a very moist climate.
C
The taiga has a short summer growing season while the tundra is warmer with a long summer growing season.
D
The taiga has a variety of animal species, but the tundra is too cold for any animals to live
Explanation: 

Detailed explanation-1: -One major difference is that the taiga biome mainly consists of trees while the tundra biome has none. The tundra biome also has two sub-categories, the Arctic tundra, and the Alpine tundra. The Arctic tundra is located above the Arctic Circle and in Antarctica.

Detailed explanation-2: -The Tundra region is limited to the northern hemisphere solely. The reason behind this is there is no land mass in the southern hemisphere that has an appropriate climate for a tundra region. The plant species in the Tundra region have a particular characteristic, and they grow very low on the ground.

Detailed explanation-3: -The appearance of trees is the most noticeable visual distinction between taiga and tundra. The taiga has a dense forest of conifers such as pine and spruce, while trees are entirely absent in the tundra. This is due in part to a shortage of water in the tundra, but it is also a product of permafrost.

Detailed explanation-4: -Conifers have adapted to survive the long, cold winters and short summers of the taiga. Their needles contain very little sap, which helps prevent freezing. Their dark color and triangle-shaped sides help them catch and absorb as much of the sun’s light as possible.

Detailed explanation-5: -The coniferous forest biome is usually called the taiga or boreal forest. This forest is dominated by large coniferous trees (trees that produce cones instead of flowers), such are pine, spruce, and fir.
