How does respiration in amoeba and hydra occur through diffusion?(OR)W

1.	How does respiration in amoeba and hydra occur through diffusion?(OR)What are the similarities in respiration of amoeba and hydra?
Answer» 1. Amoeba and hydra are aquatic organisms. 2. Respiration in them occurs through diffusion. 3. As oxygen is used by these organisms in respiration, its concentration is reduced in cytoplasm. Hence oxygen diffuses into cytoplasm from surrounding water. 4. During respiration CO₂ is continuously produced, its concentration increases in thecytoplasm, hence it diffuses into surrounding water.
