Explanation:

Eutrophication is the process of increased productivity of a lake as it ages: This statement is correct. Eutrophication is the process of increased productivity of a lake as it ages. Often this process is greatly accelerated by human influence and is termed cultural eutrophication. The increase in nutrient supply from human activities usually results in an increase in the biological production that occurs in the lake.

Duck feeding is one of the reasons behind Lake Eutrophication: This statement is correct. Duck feeding or the input of nutrients from various sources, including waterfowl, agricultural runoff, and human activities, can contribute to eutrophication by adding excess nutrients to the water.

Planktonic growth has the highest productivity in the Eutrophic stage: This statement is correct. Eutrophication often leads to increased planktonic growth, particularly of algae, due to the availability of excess nutrients. This can result in algal blooms and other ecological changes in the water body.
