WILL MARK BRAINLIESTRyan conducted a 6-day study observing the effects of an organic plant food on the growth of his sprouting bean plant. He tracked these two pieces of information:

• the height of the plant over time
Ryan found that the amounts of plant food remaining decreased and equal amounts each day, and he use the entire 72 mL by the end of his study.
