Statement I:The digestive system of frogs consists of both alimentary canal and digestive glands.

Statement II:The alimentary canal in frogs is short because they are herbivores.

Only statement I is correct.

The correct answer is Option (1) –Only statement I is correct.

The digestive system of frogs consists of both alimentary canal and digestive glands.The statement is correct. The digestive system of frogs indeed includes both the alimentary canal and digestive glands. The alimentary canal is a pathway through which food passes and includes organs such as the mouth, oesophagus, stomach, and intestine. Digestive glands, such as the liver and pancreas, contribute enzymes and substances for the digestion process.

The alimentary canal in frogs is short because they are herbivores. The statement is incorrect. The alimentary canal in frogs is short not because they are herbivores but because they are carnivores .The length of the intestine is reduced in frogs, and they are described as carnivores. Their diet primarily consists of animal matter, and the short alimentary canal is adapted to the digestion of a carnivorous diet.
