C. Independent variable: The number of days; Dependent variable: The number of birds.
D. Independent variable: The type of bird seed; Dependent variable: The type of birdfeeder.

Answer 1

The independent variable in the experiment is the type of bird seed, and the dependent variable is the number of birds that come to the bird feeder.

Step-by-step explanation:

In the experiment 'What bird seed will attract more birds to my bird feeder?' the independent variable is the type of bird seed being tested. The dependent variable is the number of birds that come to the birdfeeder in a day. The independent variable is what is being changed by the experimenter, while the dependent variable is what is being measured or affected as a result of the changes in the independent variable. In this case, the experimenter changes the type of bird seed (independent variable) to see the effect on the number of birds that visit (dependent variable).

To answer the question, the correct choice is B. Independent variable: The type of bird seed; Dependent variable: The number of birds.
