Answer 1

The correct option is B 1-->2-->3-->4-->5

Evergreen forest has a wide variety of vegetation. Creepers, shrubs and giant trees that seem to reach the sky ! This variety results in a multilayered structure. At the bottom, you have the forest floor. This layer is dark and damp and receives less than 2% of the sunlight. Above this layer is the shrub layer. This layer receives about 5% of the sunlight and extends from 1.5m to 5m from the forest floor. After this layer comes the understory. The understory extends upto a height of 20m from the forest floor. Above this layer is the canopy layer. The canopy layer forms a thick layer above the rest of the trees and eats up about 95% of the sunlight. Finally, you have the emergent layer. These trees tower over the rest of the forest and extend to heights of up to 60m.
