Hi there!
Great question!
There are different organisms on Earth and they all get energy differently.
For example, a plant gets its energy from the sun. The sun shines down on it, giving the plant energy to grow.
On the other hand, a wolf would get its energy from the food it eats. When the wolfs belly is full, it has more energy to run around and catch more of it!
Hope this helps! :D

Gravity.

The answer would be Prevent yourself from knowing what was in the pill bottles, and distributed the bottles randomly to the subjects
When researcher know which group got the treatment and which group got placebo, they might be biased. It will be better if the researcher is "blinded" and ask third party to help labeling the drug. The drug should be distributed randomly to makes the subject in control and treatment group as similar as possible.
