Question
Assertion (A): The rate of breathing in aquatic organisms is much faster than in terrestrial organisms.
Reason (R): The amount of oxygen dissolved in water is very high as compared to the amount of oxygen in air.
Options
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
Assertion (A) is true, but Reason (R) is false.
Assertion (A) is false, but Reason (R) is true.
Solution
Assertion (A) is true, but Reason (R) is false.
Explanation:
Fish and other aquatic creatures have a higher breathing rate than terrestrial organisms due to their ability to take oxygen from water through their gills. Aquatic creatures require faster breathing rates to absorb the restricted dissolved oxygen in water, which is lower than atmospheric oxygen concentrations.
