Autotrophs are organisms that can produce their own food from inorganic molecules. They are also known as producers. Plants are the primary autotrophs on Earth, using the process of photosynthesis to convert sunlight, carbon dioxide, and water into glucose and oxygen. Some bacteria and certain protists are also autotrophic.
Heterotrophs, on the other hand, are organisms that cannot produce their food and must consume other organisms or organic matter to obtain energy and nutrients. They are also known as consumers. Animals, fungi, and most protists are heterotrophs.
Therefore, not all plants and animals make their food. Plants are autotrophs, while animals and most other organisms are heterotrophs.
