Activity
Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in
compost bins, forming a dirt-like substance that's rich in nutrients. The next season, farmers use this
substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer
formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in
unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to
grow faster and taller than his artificial fertilizer. Explain independent and dependent variables

Please find the explanation of independent and dependent variables below using the experiment in this question.

Explanation:

Independent variable is the variable that the experimenter changes or manipulates in an experiment while the dependent variable is the variable being measured in the experiment.

According to this question, a biology student who has grown tomato plants for several years wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer, which he used previously.

In this case, the "natural compost" is the independent variable while the dependent variable is how tall and fast the tomato plant will grow. Hence, the tallness or fastness is the dependent variable.

not: both offer magnification to the atomic level.
