Jackie, an ecologist, has been studying the population of frogs in a small area of windy creek. She has been tracking the population of insect eating frogs in the summer to observe their reproduction rate during the months of May through August. This year, a tannery* opened upriver. Jackie has noticed the water has an orange hue and the frog population is different than last year. At the beginning of each month, Jackie checks the water quality and she has seen an increase in pollutants in the water. Below is a graph of the frog population before the tannery opened and after the tannery opened. Tannery*: factory that makes leather Using the story and graph above, predict what will happen to the population of frogs in August. ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ What effect will the frog population have on other animals that live in the area?
