SSC GD 2023 PYQ — Question 30

The correct answer is option 3 i.e. vertically

Stratification is the vertical distribution of many species occupying various strata. In a forest, for instance, trees are found in the uppermost vertical strata or layer, shrubs in the second, and grasses and herbs in the lower layers.

• The vertical distribution of several species occupying various levels is known as stratification.
• In this procedure, the top layer is made up of trees, the second layer is made up of shrubs, and the lowest layer is made up of grasses and herbs.
• The primary feature of the layer itself is its height range.
• Strata can also refer to stratified layers of organisation.
• Because of the dense foliage found in tropical rain forests, several levels have been developed to improve creature survival.
• The vegetation is organised at ground level.
