The citizens group called "Friends of the Arcata Marsh" (FOAM) is an initiative for
1 Thermal pollution
2 Integrated waste water management
3 Reducing solid waste in landfills
4 Organic farming
Explanation:
Waste water can be treated in an integrated manner. The people of Humboldt State University, Arcata in California created an integrated waste water treatment process which involved cleaning of waste water by sedimentation, filtering and chlorine treatment, a series of 6 connected marshes of a marshland where appropriate plants, algae, fungi, bacteria were seeded in the area to neutralise, absorb and assimilate the pollutants, as the water flows through these marshes, it got purified naturally. The marshes are habitat for fishes, animals and birds. These marshes were safeguarded by a citizen group called FOAM - Friends of the Arcata Marsh.

Assertion : Eutrophication shows increase in productivity in water. Reason : With increasing eutrophication, the diversity of the phytoplankton increases.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Eutrophication is a natural process which literally means well nourished or enriched. It is a natural state in many lakes and ponds which have a rich supply of nutrients. Eutrophication become excessive, however when abnormally high amount of nutrient from sewage, fertilizers, animal wastage and detergent, enter streams and lakes causing excessive growth or blooms of microorganisms. With increasing eutrophication, the diversity of the phytoplankton community of a lake increases and the lake finally becomes dominated by blue - green algae.
