Question

B.Fish uses the air dissolved in the water for breathing. _true or false​

Answer 1

Answer:

The statement is false.

Explanation:

Aquatic animals take in the oxygen dissolved in water. The amount of dissolved oxygen in water is fairly low as compared to the amount of oxygen in the air. Therefore, the rate of breathing in aquatic organisms is much faster than in terrestrial organisms.

Answer 2

The statement that fish uses the air dissolved in the water for breathing is true.

• Unlike human beings and animals, fishes do not live on land.
• Their process of breathing is completely different than that of creatures living on land.
• The organ which is responsible for breathing, is lungs, for creatures living on land. But in case of fishes, they breathe through gills.
• For organisms living on land, the oxygen is dissolved in air. For organisms living in water, the oxygen is dissolved in water.
• The percentage of oxygen dissolved in water is comparatively lower than the oxygen dissolved in the air.
