Humans are Heterotrophic

• Heterotrophic means we cannot make our own food like plants do.

• Plants are autotrophic — they make sugar (glucose) from sunlight through photosynthesis.

• Humans (and other animals) must consume food — proteins, fats, carbohydrates, vitamins, and minerals — to get energy and nutrients.

👉 Example: When you eat rice or bread, you get carbohydrates that your body breaks down into glucose for energy.
