The dependent variable is 'Number of plants' which is the correct answer.

The independent variable is CO₂ levels in ocean water, however, the growth of plants in ocean water depends on the CO₂ levels. Higher CO₂ is level is conducive to the growth of plants.

Plants use CO₂ and water in photosynthesis to prepare food in the presence of light.

6CO₂ + 6H₂O + light energy = C₆H1₁₂O₆ + 6O₂.

Answer:Number of plants.

Explanation:

When any experiment is conducted then there are two variables in the experiment. One of the variable is independent variable that we can change according to the need of the experiment.

Then the result of the experiment is known as dependent variable which depends on the independent variable.

Here, the concentration of carbon dioxide can be changed and is known as independent variable but the number of plants that will grow in the given carbon dioxide concentrations is dependent variable.
