DENDROLOGY

Detailed explanation-1: -The lower layer of the forest formed due to different types of crowns in the forest is known as the understory. The constituents of the understorey are herbs and shrubs. The plants which are usually short and have green, tender stems are known as herbs. It is the lowest layer of understorey vegetation.

Detailed explanation-2: -Several meters below the bottom of the canopy is the understory, a layer made up of young trees, short species of trees, shrubs, and soft-stemmed plants. The understory varies a lot from rainforest to rainforest. But everywhere it is darker, there is less wind, and it is more humid than the canopy above it.

Detailed explanation-3: -The canopy is the dense ceiling of closely spaced trees and their branches, while the understory is the term for more widely spaced, smaller tree species and juvenile individuals that form a broken layer below the canopy.
