Final answer:
Examples of energy transformation include when animals eat plants, converting chemical energy from plants to animals, and when plants grow through photosynthesis, converting light energy into chemical energy. The correct answer is B. 1 and 3.
Step-by-step explanation:
The question "Which statements are examples of energy transformation" asks us to identify where energy changes from one form to another. Considering the options provided:
- Animals eat plants - This involves the conversion of chemical energy in plants into chemical energy within animals that can be used for various biological processes. It is an example of energy transformation.
- A metal pot conducts heat - This is the transfer of thermal energy, but it does not involve the transformation of energy into a different form.
- A plant grows on a sand dune - This involves photosynthesis, where plants convert light energy from the sun into chemical energy, stored in the molecules of the plant.
- The sun radiates thermal energy - This is an example of energy transfer but not a transformation as the energy is already in the form of thermal energy when radiated.
Therefore, the correct combination that includes examples of energy transformation is B. 1 and 3.
