How does a lack of dissolvable oxygen in waterways affect aquatic biodiversity?

Biology

deff fn [24]3 years ago

Answer:

I think ‘there will be less oxygen available for the aquatic life due to the microbial activity’. Too much microbial activity utilizes the oxygen dissolved in the water hence making the waters anoxic. This occurs especially after algae blooms. When the algae grow exponentially and later die, microbes that oxidize the organic matter for energy utilize the oxygen and cause dissolved oxygen in the water to deplete. This hence suffocates other aquatic life.
