How do sponges and hydra transport food and oxygen although they do not possess any circulatory system?

Answers

Answered by Namanbharti05

Answer:

Animals such as sponges and Hydra do not posses any circulatory system. The water in which they live brings food and oxygen as it enters their bodies. The water carries away waste materials and carbon dioxide as it moves out. Thus, these animals do not need a circulatory fluid like the blood.
