Question

directions: use the information in unit 3 lesson 2 and lesson 3 to answer the questions below. go to aquatic science b unit 3 lesson 2 and lesson 3. review the information you learned in these sections. 1. which of the following best describes the current growth of the human population? (1 pt) (1 point) a. exponential population growth b. decreasing population growth c. migration population growth d. imminent population growth 2. authorities in chicago are concerned about sewage discharge entering the chicago river. which pollutants would they most likely be concerned about? (1 pt)

Explanation:

1. For human population growth, current trends show a pattern where growth rate is proportional to the current population size, which matches exponential growth. Decreasing growth does not fit current global trends, migration is a movement not a growth type, and "imminent population growth" is not a standard classification of growth patterns.
2. Sewage discharge contains human waste, which introduces nutrients like nitrogen and phosphorus, along with organic matter. These nutrients cause eutrophication, making nutrients the primary pollutant concern from sewage in aquatic systems.

Answer:

1. A. exponential population growth
2. Nutrients (nitrogen and phosphorus, from organic waste in sewage)
