(iii) How the results of that test are interpreted and how they relate to
overall water quality(b) Assume that the results of the water quality test that you chose in (a) are
such that they are negatively impacting stream water quality. Describe
ONE remediation technique that could be used to reduce the
environmental impact.
(c) What are indicator species and how are they used to assess environmental
quality?
(d) Provide a specific example of an indicator species that lives in a
freshwater or riparian ecosystem and how it functions in its role as an
indicator species.
(e) Freshwater wetlands are highly productive ecosystems with complex food
webs. Complete the diagram of the freshwater food web below by drawing
arrows that show a possible direction of energy flow.
