When the bottle is hung in sunlight, vaporization takes place and when the temperature reduces through condensation, the water helps in the growth of the terrestrial life inside the terra aqua column.
Explanation:
Terra qua column or bottle biology is built to study the terrestrial and aquatic habitats.
