• Heterotroph: An organism that cannot produce its own food and relies on consuming other organic material for nutrition.
• Carnivore: An animal that primarily eats other animals. Frogs consume insects, spiders, worms, and sometimes even small fish or other amphibians.
• Insectivore: A specialized type of carnivore that primarily eats insects. This is a major part of a frog's diet, especially for smaller frog species.

Adult frogs primarily eat insects and other small animals, while tadpoles are mostly herbivorous, feeding on algae and plant matter. As they mature, their diet shifts to carnivorous.
