Characteristics that mentioned biomes have in common are:
- They are all forests, dominated by trees and other woody vegetation.
- They inhabit animal life with great microbial diversity.
- They all have big carbon sinks.
Still, trees different in a number of ways in these three biomes:
- Tropical rainforest: Trees are evergreen and have large green leaves. Canopy is multilayered and dense, so there is a little light in the forests.
- Temperate deciduous forest: Trees are deciduous, leaves are lost annually. Canopy is moderately dense, so there is more light than in tropical rainforests.
- Boreal forest: Trees are evergreen conifers with needle-like leaves. Canopy is thick and permits low light penetration.
