2. A research group has discovered that damselflies, a type of dragonfly, are * 1 point being infected by a particular type of aquatic protozoan. Both young and adult damselflies are not directly infected by the protozoan but contract the infection from the prey they eat. The graph shows the percentage of adult damselflies infected by protozoans during the summer and early fall. Which of the following conclusions is supported by the graph?

2. A research group has discovered that damselflies, a type of dragonfly, are * 1 point being infected by a particular type of aquatic protozoan. Both young and adult damselflies are not directly infected by the protozoan but contract the infection from the prey they eat. The graph shows the percentage of adult damselflies infected by protozoans during the summer and early fall. Which of the following conclusions is supported by the graph?

1. Infection in embanked ponds increased during the sampling period.

2. Protozoans were more common in creek-fed ponds than embanked ponds.

3. Protozoans reproduce more quickly in embanked ponds than creek-fed ponds.

4. Infection in creek-fed ponds remained constant throughout the sampling period.

Answer 1

Based on the given information, none of the conclusions 1. Infection in embanked ponds increased during the sampling period, 2. Protozoans were more common in creek-fed ponds than embanked ponds, 3. Protozoans reproduce more quickly in embanked ponds than creek-fed ponds, or 4. Infection in creek-fed ponds remained constant throughout the sampling period can be drawn from the graph. The graph only shows the percentage of adult damselflies infected by protozoans during the summer and early fall, but does not provide information about changes in infection rates or the prevalence of protozoans in different types of ponds.
