Question

In an experiment, adding nitrogen and phosphorus to a lake led to a significant increase in algal growth. Which of the following analyses best explains this result?

Accepted Answer

Nitrogen and phosphorus are limiting nutrients, and their addition removed the growth constraints.

Answer

Nitrogen and phosphorus are essential for algal cell wall formation, leading to increased growth.

Answer

The addition of nutrients decreased oxygen levels, causing increased algal growth.

Answer

Nitrogen alone is responsible for algal growth, while phosphorus has no impact.
