Finding the Right Word for Organisms Eating Plants and Flesh

The question asks us to find a single word that describes human beings, who are naturally able to eat both plants and flesh. This refers to an organism's diet.

Let's look at the options provided and understand what each word means:

• Cannibals: This term is used for humans who eat the flesh of other humans. This is a very specific type of diet and does not describe eating both plants and other animal flesh in general.
• Herbivorous: This term describes animals that feed only on plants. Examples include cows, deer, and rabbits. Humans eat more than just plants.
• Carnivorous: This term describes animals that feed only on flesh or meat. Examples include lions, tigers, and wolves. Humans eat more than just flesh.
• Omnivorous: This term describes animals or humans that feed on both plants and animals. The word 'omni' means 'all' and 'vorous' relates to 'eating'. This perfectly fits the description of human beings who consume both plant-based foods (like fruits, vegetables, grains) and animal-based foods (like meat, fish, dairy).

Based on the definitions, the word that correctly describes organisms, like humans, who are naturally able to eat both plants and flesh is "Omnivorous".

Additional Information on Omnivorous Diets

Omnivorous diets are common in nature. Organisms with this type of diet often have digestive systems that can process a variety of food types. Human digestive systems are adapted to break down both plant and animal materials, supporting the classification of humans as omnivores. While some humans choose to limit their diet (e.g., vegetarian, vegan), the biological capacity remains omnivorous.
