Tadpoles, the infant state of frogs, sometimes eat foods that adult frogs do not. One such example is algae with the chemical AlphaBeta. A scientist has measured the amounts of AlphaBeta in algae and in ADULT frogs to try and prove that the chemical sticks around even after the tadpoles grow into frogs. Which piece of evidence from the graph SUPPORTS this conclusion?

• The AlphaBeta has made the algae and frogs grow bigger

• The AlphaBeta concentration in algae is related to the algae concentration in frogs

• The amount of AlphaBeta in algae and frogs are unrelated
