NACA Animal Control Officers Practice Test

Which type of animal feeds on both plant and animal matter?

1. Carnivores

2. Herbivores

3. Omnivores

4. Detritivores

The correct answer is: Omnivores

The classification of animals based on their diets indicates that omnivores are those that consume both plant and animal matter. This dietary flexibility allows omnivores to take advantage of a broader range of food sources, which can be particularly beneficial in diverse environments where availability may fluctuate. For instance, omnivores like humans, bears, and many bird species can adapt their diet according to what is accessible, whether that includes fruits, vegetables, nuts, insects, or small animals. This adaptability not only supports their nutritional needs but also plays a crucial role in various ecosystems, as they can help control populations of plants and animals. In contrast, carnivores exclusively eat other animals, relying entirely on them for their dietary needs. Herbivores, on the other hand, depend solely on plant matter, and detritivores primarily feed on decomposing organic material. Each of these groups plays a unique role in their ecosystems, but it is the omnivores that bridge the gap, utilizing both plant and animal resources effectively.
