An investigation was done to see the effect of day length on the number of eggs chickens laid.
the dependent variable in this experiment is:

a) number of eggs laid
b) day length

The correct answer is A) Number of eggs laid

Explanation:

In an investigation, the factor that is being studied and can be affected by other variables is known as the dependent variable. Additionally, this is the opposite of the independent variable that is manipulated on purpose by the researchers. This implies, in the case presented, the day length is the independent variable because this is going to be manipulated by the researchers, and therefore, the dependent variable is "number of eggs laid" as this factor is the one being studied and the one that is expected to be affected by the independent variable.

it's anything that aren't producers and consumers.

explanation:

you've got to be clear on what "this" is
