Option 1 states that the rate of breathing in aquatic organisms is faster because there is a higher amount of dissolved oxygen in water compared to the amount of oxygen in the air. However, this is incorrect. Aquatic organisms rely on the oxygen dissolved in water, which is limited compared to the amount of oxygen in the air. Therefore, the rate of breathing in aquatic organisms is not faster due to a higher amount of dissolved oxygen in water.

Option 2 suggests that the rate of breathing in aquatic organisms is slower because there is a higher amount of oxygen in the air compared to the amount of dissolved oxygen in water. This is also incorrect. While there may be more oxygen in the air, aquatic organisms cannot extract it directly from the air. They need oxygen that is dissolved in water to survive.

Option 3 states that the presence of gills in aquatic organisms contributes to their faster rate of breathing. This is partially correct. Gills play a crucial role in extracting oxygen from water, allowing aquatic organisms to breathe. However, it is not the only reason for their faster rate of breathing.

Option 4 correctly states that the rate of breathing in aquatic organisms is faster because there is a lower amount of dissolved oxygen in water compared to the amount of oxygen in the air. Aquatic
