Question

Identify the scenario from the following alternatives, which is supported by the given plot.

• A. As the algae content in a lake increases, the number of fish decreases
• B. As the algae content in a lake decreases, the number of fish decreases
• C. As the algae content in a lake increases, the number of fish increases
• D. As the algae content in a lake increases, the number of fish remains constant

Answer 1

The correct option is A As the algae content in a lake increases, the number of fish decreases

The line is decreasing from left to right, so it has a negative slope.

This means there is an inverse relationship between the amount of algae and the number of fish.

In other words, as one increases, the other must decrease.
