Question

A researcher is studying the effect of different pH levels on the growth of algae in a pond. She sets up three tanks with water at different pH levels: Tank A has a pH of 5, Tank B has a pH of 7, and Tank C has a pH of 9. She ensures that all tanks receive the same amount of light, the same type of algae, and the same temperature.

After 7 days, the researcher observes the following growth results:

1. Tank A (pH 5): Minimal algae growth

2. Tank B (pH 7): Significant algae growth

3. Tank C (pH 9): Moderate algae growth

What conclusion can the researcher draw from these results?

Options

Algae grow best in highly acidic conditions.

Neutral pH (7) is optimal for algae growth.

Algae growth is not affected by pH.

Algae cannot survive in basic (pH 9) water.
