Chapter 4 Solutions — Environment

People commonly plant trees like neem, mango, banana, coconut, tulsi, and flowering trees such as gulmohar or hibiscus in their homes.

It is important to plant trees because:

— Trees produce oxygen and absorb carbon dioxide, keeping air clean.

— They provide shade, reducing heat.

— Fruit trees provide food.

— Trees prevent soil erosion and support wildlife.

— They improve mental well-being and beautify surroundings.

This is an open-ended discussion question. A well-supported answer:

Yes, the cherry tree is likely to survive because:

— Grandfather himself says, 'Cherry trees are tough,' indicating the tree has a strong natural resilience.

— Even after the goat ate all its leaves, only the main stem and two thin branches remained — the tree was not uprooted, so its root system was intact.

— In the story's Part II, the cherry tree does in fact survive — new leaves appear after the goat's damage, and the tree continues to grow.

The story reinforces the message that life, like the cherry tree, finds a way to persist through adversity.
