Organisms are divided into four groups on the basis of their water needs.What are the four groups and give an example of each?

Organisms are categorized into four groups based on their water needs:

1. Hydrophytes (water plants) – These organisms thrive in aquatic environments, such as water lilies.
2. Xerophytes (desert plants) – These plants are adapted to conserve water, like cacti.
3. Mesophytes (moderate water plants) – These require a moderate amount of water, such as corn.
4. Halophytes (salt-tolerant plants) – These can grow in saline environments, like mangroves.
