With such a release into a lake system, answer the following:(i) How will the addition of sewage affect the oxygen levels in the limnetic zone in the short-term and in the longer-term? Explain. (ii) With the addition of sewage, the number of allochthonous organisms would be expected to increase or decrease? Explain.(iii) With the addition of sewage, how (and why) would secondary productivity be impacted from the surface of the lake with depth to the benthic zone? Explain.
