When testing fertilizer on a tomato farm, one patch of soil is given fertilizer and another patch (the same size) is not. Which one is the experimental group? A. The amount of rain B. The amount of sunlight C. The fertilized soil D. The unfertilized soil

Answer: C. The fertilized soil.

Experimental group is a group of variables that can be changed or manipulated to observe their impact on the dependent or unchanged variables. Here, the experimental group is fertilizer. The experiment is done to know the impact of fertilizer on the tomato farm.

The correct answer is option C.

When testing the fertilizer on tomato farm, one patch is given with fertilizer and other is not given with the fertilizer then the effect can only be seen in the tomato farm that is having the fertilizer in it. The fertilizer here is dependent variable. The fertilized soil here will show the affect of fertilizer on tomato farm so it is experimental group.
