Explanation:

Both statements about the Banyan tree are correct:

It is the National tree of India and is typical of tropical and subtropical climates.

The tree starts its life as an epiphyte, which means it grows on other plants.

Epiphyte, also called air plant, any plant that grows upon another plant or object merely for physical support. Epiphytes have no attachment to the ground or other obvious nutrient source and are not parasitic on the supporting plants.
Banyan or Indian Fig tree is the national tree of India.
