In the given case, the independent variable will be the amount of nitrogen present in the fertilizer.

Explanation:

In an experiment, an independent variable refers to the variable, which is controlled or changed, it is the variable that is used by the researcher to examine their dependent variable. In the given case, the amount of nitrogen present in the fertilizer will be the independent variable, as it is not reliant upon any other kind of variable.

Also, from being not dependent on other variables, it is a variable on which other variables relies upon, and in the given case, it will be the number of blossoms and the number of leaves grown on the tomato plant with the application of the fertilizer.
