Detailed explanation-1: -The subarctic is an area of the Northern Hemisphere that lies just south of the Arctic Circle. The taiga lies between the tundra to the north and temperate forests to the south. Alaska, Canada, Scandinavia, and Siberia have taigas.

Detailed explanation-2: -Tropical rainforests have an emergent layer of tall trees over 40 m tall, an overstory of trees up to 30 m tall, a sub-canopy layer of trees and tall shrubs, and a ground layer of herbaceous vegetation. Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.

Detailed explanation-3: -These trees have many different types that all grow decently tall ranging from 60-80 feet tall. They tend to grow in pairs of clusters.

Detailed explanation-4: -The tundra and taiga biomes are both found in very cold climates, but they do have some key differences. 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.

Detailed explanation-5: -Forests are dominated by trees, and cover about one-third of the Earth. Forests contain much of the world’s terrestrial biodiversity, including insects, birds, and mammals. The three major forest biomes are temperate forests, tropical forests, and boreal forests (also known as the taiga).
