Question

A tree cover and undergrowth (bushes, plants, grasses and creepers) which grow with little interference from human beings is called _____.
A) Timber
B) Wood
C) Shelter
D) Forest

Answer 1

Hint: Any woody plant with numerous stems, none of which is dominant, and which is less than 3 m (10 feet) tall is called a shrub. It's called a bush when it's densely branching and dense. Arborescences, or treelike shrubs, range in height from 3 to 6 metres and are intermediate between shrubs and trees. Trees are woody plants that are more than 6 metres tall, have a dominating stem or trunk, and a distinct crown shape.

Complete answer:
The forest floor, understory, and canopy are the three layers that make up a forest. Soil, dead plants and animals, and small plants like grasses and wildflowers make up the forest floor. The understory, also known as the shrub layer, consists of small trees or bushes that grow beneath the forest canopy but above the forest floor, without piercing it to a large amount. The canopy of the forest is made up of the leaves and branches of the tallest trees.

Despite the fact that the term "forest" is widely used, there is no universally accepted accurate meaning, with over 800 different definitions used around the world. Although the presence of trees is typically used to define a forest, several definitions allow for an area devoid of trees to be deemed a forest if it has previously grown trees, will grow trees in the future or was legally declared as a forest regardless of vegetation type.

Therefore the correct answer is option ‘D’.

Note: Except where natural fire frequency or other disturbance is too great, or where the environment has been altered by human activity, forest ecosystems can be found in all locations capable of supporting tree growth, at altitudes up to the tree line.
