Final answer:
Through the water cycle and nutrient cycling, it is possible to have matter in your body that was once part of the body of historical figures like George Washington or Thomas Jefferson.
Step-by-step explanation:
The correct answer is c. Through the water cycle and nutrient cycling.
Water is constantly recycled through the ecosystem, meaning that the water you drink today has been around for millions of years. This means that you could be drinking water that was once consumed by historical figures like George Washington or Thomas Jefferson.
Similarly, nutrients like carbon, hydrogen, oxygen, and nitrogen are cycled through the Earth in different forms. These nutrients are taken up by plants, which are then eaten by animals, and eventually released back into the environment through processes like decomposition. This continuous cycling of nutrients allows for the possibility that the matter in your body could have once been part of the body of someone like George Washington or Thomas Jefferson.
