heterotrophic

/ˌhɛtərəˈtrofɪk/

In biology, anything heterotrophic eats other animals or plants, rather than making its own food. Unless your cat can synthesize its own nutrients from sunlight, Mr. Flufferpants is heterotrophic.

Because you don't fulfill your nutritional requirements through photosynthesis, instead eating plants (and animals, unless you're a vegetarian), you are heterotrophic. Animals, some fungi, and some bacteria are described this way, because they can't create energy from sunlight or chemical reactions. The term heterotrophic comes from hetero-, "other or different," and trophe, "nutrition."
