The four layers of the canopy layer are: The Emergent Layer: The tallest trees of up to 70 meters height are found in this layer. Perhaps the most obvious adaptation of this sort is seen in plants that climb from the ground to the uppermost canopy along other plants by using devices that resemble grapnel-like hooks. An unusual mix of trees of different sizes is found in the tropical rainforest, and those trees form several canopies below the uppermost layer, although they are not always recognizably separate layers. However, tree seedlings and saplings are abundant; their straight stems reach toward the light but receive too little energy to grow tall enough before food reserves from their seeds are exhausted. 2023 Population Education.

Based on these data, the rmax for this population was determined to be 0.57. The primary layer is the canopy where about 70 to 90 percent of all rainforest life resides. During periods of drought, epiphytes undergo stress as water stored within their tissues becomes depleted. This shallow rooting pattern increases the likelihood of tree falls during storms, despite the support that many trees receive from flangelike plank buttresses growing radially outward from their trunk bases.
