[ 1 ] [ 2 ] [ 3 ] In forest ecology , the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes , lianas , arboreal animals , etc.).

[30] A sapling is a young tree. [31] Many tall palms are herbaceous [32] monocots, which do not undergo secondary growth and never produce wood.
Amazon rain forest biotope. A biotope is an area of uniform environmental conditions providing a living place for a specific assemblage of plants and animals. Biotope is almost synonymous with the term "habitat", which is more commonly used in English-speaking countries.

Tree Top, Inc. was the first grower-owned fruit processing cooperative in the United States. 1,100 apple and pear growers in Washington, Idaho, and Oregon own the cooperative, with the majority of the growers from Washington.
The crown of a woody plant (tree, shrub, liana) is the branches, leaves, and reproductive structures extending from the trunk or main stems. Shapes of crowns are highly variable. The major types for trees are the excurrent branching habit resulting in conoid shapes and decurrent (deliquescent) branching habit, resulting in round shapes.
Early phylogenetic tree by Haeckel, 1866. Groups once thought to be more advanced, such as birds ("Aves"), are placed at the top. The idea of a clade did not exist in pre-Darwinian Linnaean taxonomy, which was based by necessity only on internal or external morphological similarities between organisms.
