D) Decrease
Explanation:
When algae dies, decomposing organisms will work on them and this cause the reduction in the amount of dissolved oxygen in the water.
- The number of decomposers in the body of water will increase rapidly.
- To decompose they need a lot of oxygen which they will remove from the water.
- They use the oxygen for their own life activities and they sometime combine it with the algae matter to release nutrients back to the water and atmosphere.
- The bloom of the micro - organisms will lead to decrease in dissolved oxygen in water.
