A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsius, and the number of insect larvae (y) in the water:
What does the peak of the graph represent?
The number of larvae in the water is greatest at 450 degrees Celsius.
The number of larvae in the water is greatest at 5 degrees Celsius.
The least number of larvae in the water is 450.
The least number of larvae in the water is 5.
