Added sugar contains no essential nutrients but is high in calories.Regularly consuming an excess of added sugar can lead to compulsive overeating. It is also linked with health conditions such as obesity, metabolic syndrome, type 2 diabetes, and inflammatory diseases.

Answer: c. Lawn fertilizer that washes into neighborhood ponds likely causes algae to become more abundant.
Explanation:
Eutrophication is a natural phenomena in which the algal growth occurs in the water body due to increase in concentration of the fertilizers and manures being drained from the agricultural land into water. This causes decrease in oxygen level in water, and the aquatic animals in water will not survive due to scarcity of water.
According to the given situation, the growth of algae in the neighboring ponds is due to the drainage of lawn fertilizers into the neighboring ponds being washed from the lawns. This causes algae to grow abundantly in ponds.
