Answer:
Colder water temperatures
Step-by-step explanation:
Colder water temperatures are most likely the limiting factor in this situation. Algae growth is typically favored by warm temperatures, and during the summer months, the warm water provides an optimal environment for the rapid growth of algae in a pond. As winter approaches and temperatures drop, the growth of algae slows down and the population drops rapidly due to the less favorable conditions. While increased acidity or an excess of nutrients can also impact algae growth, colder water temperatures are likely the primary limiting factor in this scenario.
