Strawberries left in a warm, moist environment will eventually rot and become covered in mold fungi.
Describe how mold fungi decompose these strawberries.
Strawberries are often treated with natural plant essential oils (such as thyme oil, clove oil, and peppermint oil) which act as organic fungicides to prevent spoilage.
Design an investigation to find out which of these three essential oils is best at preventing the decomposition of harvested strawberries.
Your answer should include experimental details and be written in full sentences.
