Question

Adult Frog is
A. Carnivorous
B. Sanguivorous
C. Omnivorous
D. Graminivorous

Answer 1

Hint: Frogs are members of class Amphibia. Amphibians are cold-blooded vertebrate animals that need water or a moist environment to survive. They are ectothermic therefore cannot regulate their own body heat, so they depend on sunlight to become warm and active.

Complete answer:
An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail. They have glandular skin, with secretions. Skin colour carries from well-camouflaged dappled brown, grey to green and various patterns of bright red or yellow and black to show toxicity and ward off predators. They live in fresh water and on dry land as well. Few species are adapted for living underground or in trees.
Adult frogs have a carnivorous diet consisting of small invertebrates, but few species are omnivorous as well. Frog skin has a rich microbiome which is important to their health. They have the ability of converting what they eat into body mass.
Most of the frog species are carnivorous as adults, preying on invertebrates, including arthropods, worms, snails, and slugs. Some frogs use their sticky tongues to catch fast-moving prey, while others push food into their mouths with their hands. A few species also eat plant matter. Adult frogs are attacked by many predators.

So, the correct answer is A, carnivorous.

Note: Tadpoles are herbivorous, feeding on algae, detritus, plants and some small invertebrates, but become carnivorous when their back legs develop. Some frogs feed on invertebrates but their feeding habits change throughout their lives. Adult common frogs feed on invertebrates of a suitable size, and catch their prey by long, sticky tongues, although they do not feed at all during breeding season. Preferred foods include insects, snails, slugs and worms.
