Final answer:
Demeter's Roman name was Ceres, which is still honored through the word cereal, signifying a direct link to agriculture and the goddess's mythological significance.
Step-by-step explanation:
The Roman name for the Greek goddess Demeter was Ceres. This name continues to be honored today, most notably through the word cereal, which comes from Ceres and reflects her association with grains and agriculture. In ancient mythology, Demeter/Ceres was the goddess of harvest and fertility, deeply tied to the earth's bounty and the cycle of life and death, as illustrated by the famous myth of her daughter Persephone's abduction by Hades, which led to the changing seasons. The legacy of Demeter's Roman name endures in the agricultural industry and when people partake in the daily ritual of eating cereal.
