Scientists have been studying the size of three populations in a grassland. In this ecosystem, hawks (a type of large bird) eat sparrows (a type of small bird), and sparrows eat seeds from buckwheat. The data showed that all three populations were stable. Then the hawk population increased suddenly. What will likely happen to the size of the sparrow population as a result?

•what conclusions can you make about the relationship between the volume of a gas and its temperature? • what conclusions can you make about the relationship between the volume of a gas and its pressure? • what possible variables have you not accounted for? as you did the procedures, is it possible that the atmospheric pressure may have changed? if it did change over the course of your experiment, then how would your results have been affected?
