Verified step by step guidance

1. Step 1: Understand the term 'omnivore' by breaking it down. The prefix 'omni-' means 'all' or 'everything,' and '-vore' refers to eating or consuming. Therefore, an omnivore is an organism that consumes a variety of food sources.
2. Step 2: Compare the diet of omnivores to other types of consumers. Herbivores eat only plants, carnivores eat only animals, and omnivores eat both plants and animals. This distinction is key to understanding the diet of omnivores.
3. Step 3: Consider examples of omnivores in nature. Humans, bears, and raccoons are common examples of omnivores because they consume both plant-based foods (like fruits and vegetables) and animal-based foods (like meat or insects).
4. Step 4: Eliminate incorrect options based on the definition of omnivores. Omnivores do not eat only fungi, only plants, or only animals. They eat both plants and animals, which makes them versatile consumers in ecosystems.
5. Step 5: Confirm the correct answer by aligning it with the definition and examples provided. The correct description of the diet of omnivores is: 'They eat both plants and animals.'
