Detailed explanation-1: -In this experiment, the addition of fertilizer is the independent variable manipulated by the scientist. Plant height is the dependent variable that responds to the change in the independent variable. Each plant is exposed to an equal amount of sunlight, so sunlight is the control variable.
Detailed explanation-2: -For this question, the amount that the plants grow is what is being measured, so this is the dependent variable. The dependent variable depends on the independent variable. The amount that the plants grow depends on the amount of sun they get.
Detailed explanation-3: -Independent Variables Volume of water given to plants. Nitrogen or phosphorus concentration in soil. Duration or intensity or wavelength of light plants are exposed to. Concentration or type of fertilizer.
Detailed explanation-4: -In the plant experiment shown in the Figure below, the dependent variable is plant growth. The variable that affects the dependent variable is called the independent variable. In the plant experiment, the independent variable could be fertilizer-some plants will get fertilizer, others will not.
