Question

Q2. A company is growing algae in big tanks to make fish food. However, the algae is not growing very quickly, and they suspect either phosphorus, nitrogen, or iron is limiting. What could the company do to figure out which nutrient is limiting?


Add phosphorus to one tank, nitrogen to another, and iron to a third, and see which treatment increases algal growth.

Add phosphorus, iron, and nitrogen to all tanks, and see which nutrient increases algal growth.

Add phosphorus to all tanks, because phosphorus is the nutrient that limits algal growth.

Add nitrogen to all tanks, because nitrogen is the nutrient that limits algal growth.

Explanation / Answer

A company will add phosphorus to one tank, nitrogen to another, and iron to a third, abd observe which treatment increases algal growth. If you will add all nutrient to one tank then you cant determine which factor increases algal growth. Phosphorus and nitogen both are critical for algal growth , so you can say which factor is limiting. Here, the answer is A , in the presence of all 3 nurient in separate tank help you to determine algal growth.
