Why do frogs eat insects?

Frogs eat insects primarily as a source of nutrition, as insects provide essential proteins, vitamins, and minerals that are crucial for their growth and survival. Being carnivorous, frogs have evolved to be efficient hunters, using their long, sticky tongues to catch insects quickly. This diet also helps control insect populations in their ecosystems, contributing to ecological balance. Additionally, feeding on insects supports their energy needs for activities such as mating, movement, and thermoregulation.
