Answers
Answer:
i do not know the answer sorry
Answer:
Sponges and hydra live in water and do not have blood or any circulatory system. In simple multicellular organisms like Hydra, the transportation of material from cell to cell takes place through simple diffusion. Sponges have water transport system or canal system that helps in transportation of materials.
Explanation:
They are surrounded by water which brings in and out the food and oxygen required by them through simple diffusion.
Animals such as sponges and Hydra do not possess 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.
