Jimmy and Karen conducted an experiment comparing tomato plant growth and the amount of fertilizer applied to each plant. The plants were kept in the same location, received the same amount of water, and the pots contained the same type of soil. They concluded that the more fertilizer they applied, the better the plant growth. What comment would you make about their conclusion?

AThe conclusion matched the data.
BThey should omit the data for Plant 5 and keep their original conclusion.
CA better conclusion would be that fertilizer amount had no effect on plant growth.
DThe highest fertilizer rate resulted in a dead plant; they should change their conclusion.

I think that judging by the amount of fertilizer used and how it killed the plant that your answer would likely be D.

The correct answer is D) The highest fertilizer rate resulted in a dead plant; they should change their conclusion.


The plants increased their growth when the amount of fertilizer added increased until reaching an optimum point of fertilizer quantity, from which greater amounts of fertilizer had a detrimental effect on the growth of the plants and even caused their death.


The optimum occurred when adding 3 grams of fertilizer to the plant. When applying 4 grams to the plant the yield of the fertilizer decreased and when applying 5 grams to the plant, the plant died.
