Question

A plant growing on a forest floor
A. Has shallow roots
B. Requires low light
C. Has a deep taproot
D. Requires strong light
E. Requires moist soil

Answer 1

Hint:Forest floor refers to the base of the forest i.e., the base made up of the soil. All plants require the support of the soil to grow. Moreover, the floor of the forest is covered by a very thick dense canopy.

Complete answer:
The base or the forest floor is covered by the thick dense canopy of the tall trees in a forest. Due to this reason the forest floor receives very minimal light. This is because the tall trees block the maximum portion of the light. Thus, only rays of light are able to enter through the canopy. Since the height of trees differs then several layers are created which filter the light subsequently passing from them. This is known as stratification. The plants with the lowest stratification or the minimum height are found most close to the forest floor. These plants are adapted to survive with very low levels of light. These plants have very dark green leaves due to the high amount of chlorophyll that enables them to absorb as much sunlight as possible. If these plants required strong sunlight then they would not survive on the forest floor.
Thus, based on the above information we can conclude that a plant growing on a forest floor requires low light.

Hence, the correct answer is an option (B).

Note: Stratification of forest refers to the vertical distribution of the different species of plants that occupy different levels. It is the structure that is recognized in spatial arrangements for the members of the different communities. In a forest, the following stratification is present –
The top layer or the top strata consists of trees.
The second layer or the middle strata consists of shrubs.
The bottom layer or the last strata consists of herbaceous plants and grass.
