Delicious77 [7]

Answer:

B. The apple orchard releases toxic chemicals into the water of the  bay.

Explanation:

Option B is the correct answer. It is the most likely explanation for the results in the graph.

From the graph, we can see that the population of the fishes sharply dropped. Since the fertilizer is applied to the apple orchard and the orchard was planted beside the bay, during the rain it is possible that the water has washed some of the fertilizers into the bay. The chemicals used in making fertilizer are harmful and toxic.

This reveals that the toxic chemicals released from the apple orchard are responsible for the decline in the population of the fish.
