Answer:
<em>The number of fish would decrease.</em>
Explanation:
Ecological hypoxia can be described as a condition in which the oxygen level drops to such low levels in the aquatic ecosystem that it is no longer able to support aquatic life. In such a condition, the number of fishes declines at a rapid rate because fishes require oxygen as an essential element. Also, those fishes which do not have better adaptations to survive might get totally wiped out from the aquatic ecosystem.

The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.
The rate of breathing can be measured by counting the number of breaths in one minute. The depth of breathing can be measured using a spirometer (a device that measures the volume of air inhaled and exhaled).
To investigate the effects of exercise on breathing, record the rate of breathing for a few minutes when the person is at rest. After they do some exercise, record their rate of breathing every minute until it returns to the normal resting value.
