Explanation

• Omnivores can be both secondary and tertiary consumers, depending on their diet and position in the food chain.
• They can eat primary consumers (herbivores) as secondary consumers, and also eat secondary consumers (other carnivores or omnivores) as tertiary consumers.

Explanation

• Omnivores are consumers that eat both producers (plants and algae) and consumers (other animals).
• They have a varied diet that includes both plant and animal matter.
• Examples of omnivores include humans, bears, pigs, and chimpanzees.

Explanation

• Tertiary consumers are animals that eat primary and secondary consumers.
• They are typically apex predators that have no natural predators in the wild and are at the top of their food chain.
• Examples of tertiary consumers include lions, sharks, bears, and humans.

Explanation

• Carnivores are secondary consumers that eat primary consumers (herbivores).
• In this case, birds and mice are primary consumers (herbivores) that eat plants and plant products.
• Carnivores that eat birds and mice are secondary consumers.

Examples of carnivores that might eat birds and mice include:

• Hawks and owls (birds of prey)
• Foxes, wolves, and cats (mammals)
• Snakes and lizards (reptiles)
