Frogs and toads are carnivores, which means that they will eat meat. Small to medium sized frogs eat insects such as flies, mosquitoes, moths and dragonflies. Larger frogs will eat larger insects like grasshoppers and worms. Some large frogs will even eat small snakes, mice, baby turtles, and even other smaller frogs. Hence, the correct answer is option 'C'.

Frogs are Carnivores

Frogs are classified as carnivores, which means they primarily feed on other animals. Let's explore why frogs are considered carnivorous creatures in detail.

1. Anatomy and Digestive System
Frogs have a unique anatomy and digestive system that is adapted for a carnivorous diet. Their mouth is equipped with a specialized tongue that can be rapidly extended to capture prey. The tongue is covered in sticky saliva, allowing the frog to catch and hold onto its prey. Once captured, the prey is swallowed whole.

2. Diet
The diet of frogs primarily consists of small invertebrates such as insects, spiders, worms, and other small animals. They are opportunistic feeders and will consume any prey that they can overpower and fit into their mouth. Some larger frog species may even consume small vertebrates like fish, birds, or rodents.

3. Feeding Behavior
Frogs are typically ambush predators, meaning that they rely on stealth and patience to catch their prey. They often wait patiently for their prey to come within striking distance before rapidly lunging forward to capture it. Some frogs also have the ability to project their sticky tongues outwards with great speed and accuracy to catch flying insects.

4. Adaptations for Carnivory
Frogs have several adaptations that aid them in their carnivorous lifestyle. Their eyes are positioned on top of their head, providing them with a wide field of vision to detect prey. They also have excellent hearing and can locate prey by sound. Their strong hind legs allow them to jump quickly and catch prey. Additionally, frogs have a specialized respiratory system that enables them to breathe while swallowing their prey.

5. Exceptions
While most frogs are carnivorous, there are a few exceptions. Some species, known as foam-nest frogs, have a unique reproductive strategy where they lay their eggs in foam nests and the developing tadpoles feed on the foam, which is rich in nutrients. These frogs are considered to have a herbivorous larval stage.

In conclusion, frogs are classified as carnivores due to their anatomy, digestive system, diet, feeding behavior, and various adaptations for capturing and consuming prey. They play a crucial role in ecosystems by controlling populations of insects and other small animals.
