15 Which of the following is a negative consequence of aquaculture? A Protein-rich food is provided to billions of people B Pressure on wild fish populations is reduced. B C Excessive amounts of nitrogen and phosphorus can leak from the location. c D Other species (by-catch) may be accidentally removed during harvest D (1) Mark for Review

Answer 1

The correct answer is:**C. Excessive amounts of nitrogen and phosphorus can leak from the location.**### Explanation:Aquaculture, while beneficial in many ways, can have negative environmental consequences. One significant issue is the release of excessive nutrients like nitrogen and phosphorus into surrounding water bodies. These nutrients often come from uneaten fish feed and fish waste. When they accumulate in the environment, they can lead to problems such as **eutrophication**, which causes algal blooms, oxygen depletion, and harm to aquatic ecosystems.- **A** and **B** are positive outcomes of aquaculture.- **D** refers to bycatch, which is more commonly associated with traditional fishing methods rather than aquaculture.
