Why is dissolved oxygen in water important for aquatic animals?
Answer and explanation
Correct answer: For respiration
Aquatic animals obtain oxygen that is dissolved in the surrounding water, using organs such as gills or other respiratory surfaces. This oxygen supports cellular respiration, which releases usable energy from food for movement, growth, and other life processes. It does not make water sweet, change its colour, or turn it into a solid. Therefore, dissolved oxygen is important primarily for respiration.
