Levi decides to examine the effect of fertilizer on the growth of tomato plants. he chooses four plants for his experiment and applies varying amounts of fertilizer to three of them. he does not apply fertilizer to one plant. over a 15-day period, the plants receive fertilizer on days 1, 4, 7, 10, and 13. levi measures the height of all of his plants with a meterstick on days 3, 6, 9, 12, and 15. he also makes sure to hold all experimental factors constant except for the fertilizer. what is the independent variable in levi's experiment on tomato plants?

The independent factor would be the amount of fertilizer.

Explanation:

An independent variable is the one that changes and has an effect on the dependent variable. Meaning, the independent variable is not dependent on any factor.

In above question, the independent variable is fertilizer because the height of the plant depends on the amount of fertilizer used for it.  The more the fertilizer is used, the higher the plant will grow.
