Question:

How does the nutrient content in lakes contribute to overall health of the ecosystem?

Sara S.
Answer:

The accumulation of nutrients in lakes (eutrophication) can be detrimental to fish and other aquatic animal life. These conditions support plant growth, but the decomposition of plants deplete the water of oxygen. Conversely, lake systems low in nutrients (oligotrophic lakes) tend to have higher dissolved oxygen concentrations leading to less aquatic plant life.

Answer:

The p-value of a statistical test gives you the probability of obtaining results at least as extreme as the observed results. In other words, a small p-value indicates that you should reject the null hypothesis.
