Maximum harm to a tree is caused by
-
- loss of half of its leaves
- loss of all leaves
- loss of half of its branches
- loss of its bark
- loss of half of its leaves
Correct Option: B
Loss of all leaves lead to maximum harm as the tree loses its ability to perform photosynthesis so necessary for food manufacturing. Besides, loss of its bark will also be dangerous as it is the only part of a tree that is really alive. There is thin layer of cells right under the bark. If the bark is gone that layer dries out and dies.
