Question

For his class project, Mike needs to collect samples of algae. In which section of a river is Mike most likely to find algae?

Answer 1

The most likely place to find algae is in the middle.

Answer 2

Answer: Option A

Explanation: There will be more deposition found in the middle of the river as it will have more deposition of fertilizers containing nitrogen and phosphorous.

The more will be the deposition, more will be the algal bloom. The sections of the river having running water will have little or no algal bloom as there will be less deposition of the substances favoring algal bloom.
