Answer:

Second Option (the color of the feeder)

Explanation:

Answer 2

An independent variable is a variable that is controlled in the experiment to test whether there will be an effect on the dependent variable. So in the experiment, the independent variable is the color of the feeder because Jamal wants to know if there is an effect if he uses red feeders on the hummingbirds. This is the one being controlled by Jamal because he can use a variety of colors of the feeders.
