The manipulated variable in growing plants could be the type of fertilizer used, the amount of water given, the light exposure, or the temperature of the environment. It is the variable that the researcher purposely changes to observe its effect on plant growth.
In a tomato plant experiment, the manipulated variable is the factor that the researcher intentionally changes, such as the amount of sunlight, water, or fertilizer given to the plant. This variable is controlled by the experimenter to observe its effects on the plant's growth and development.
Oxygen is the gas given out by green plants during photosynthesis.
The name given to plants because they make their food through photosynthesis is producer. Only plants can be producers. Hope it helped! :)
Why must controls (such as plants given water only) be used in the fertilizer experiment
