remaining half ate cornflakes. the researcher then recorded the number of aggressive acts displayed by the children in a one-hour play period after breakfast. in this experiment:
In this experiment "the type of cereal is the independent variable, and the number of aggressive responses is the dependent variable." There are two types of variables, dependent and independent variable. The dependent variable is 'dependent' on the independent variable. A dependent variable is the one which is being measured in any experiment and independent variable is the one which is changed in that experiment to examine the consequences for the dependent variable.

Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.
