Answer: heterotrophic omnivore
Step-by-step explanation:
Autotrophic organisms are those which can prepare their own food either by chemosynthesis or photosynthesis. These includes plants, some protists and some microbes. Heterotrophs are the organisms that cannot prepare their own food and dependent upon others for their food needs. They can depend upon plant or animal food. Omnivores are the organisms that can take both plant and animal as their food source.
Skunks can eat both plant and animal based foods and they cannot prepare their own food thus they can be categorized into heterotrophic omnivores.
