Q.Write any three economic importance of frog.

Frogs are economically important as research/teaching model animals, as natural pest-control agents that protect crops, and as a source of food (frog legs) with export value.

1. Research and education: Frogs (e.g. Rana species) have long been used as standard laboratory animals for studying physiology, anatomy, embryology, and for dissection in biology teaching, because their organ systems are relatively simple to study and broadly comparable to those of other vertebrates.

2. Biological pest control: Frogs feed voraciously on insects and other small pests (such as crop-damaging insects and mosquito larvae), helping to naturally control agricultural pest populations and reducing the need for chemical pesticides.

3. Food and export value: In several regions and countries, frog legs are considered a delicacy and are consumed as food; frog leg meat is also exported, generating economic revenue for local communities.
