The selection of dependent, independent, and controls in the experiment are number of fishes that survived, different sized aquariums, and negative controls are the maintenance, food, water temperature, respectively.
Further Explanation:
A dependent variable defines as the variable which is being tested as well as measured in the scientific experiment. This variable is known to be dependent on the independent variable. In this case, the size of the population is the dependent variable.
The independent variable refers to that variable that is altered or controlled in a scientific experiment in order to check the effects on the dependent variable. In this case, habitat space is an example of this variable
Lastly, a controlled variable refers to the variable which is constant and it is unchanged throughout the course of the experiment. In this case, type, as well as amount of food, cleanliness of aquarium as well as water temperature, are controlled variables.
At the end of the experiment there are no controlled sets in this and these sets are usually known to be the reference point in experimental setups.
