Answer 1

Hint Birds come under the class of aves. They are characterized by the beaks and the feathers present on their body. Chondrichthyes is a class of fish that consists of cartilaginous fishes. Mammalia is a vertebrate animal and consists of mammals. Class Reptilia consists of reptiles and amphibians. Osteichthyes consist of fishes mainly bony fishes.

Complete answer:
-Aptenodytes are penguins. They belong to the class aves. They are flightless birds. One of the species of penguins has gone extinct. They are of a long size and have a slender shaped bill. They consist of the emperor and the king penguin. They are the ones which can dive for long distances.
-Hemidactylus consists of the geckos. It belongs to the class of Reptilia. They are found in the tropical and subtropical regions of the world. The species are commonly known as house geckos as they are found in and out of the homes. They can easily coexist with humans. Hemidactylus consist of approximately 47 species.
-Carcharodon consist of sharks and are present in the class Chondrichthyes. Some members of the genus are already extinct in nature. The only extant member of this genus is the great white shark. It is one of the greatest predators present in an ocean. They also help in clearing water due to their high speed which is known as breaching.
-Pteropus are the largest living bats present in the world. They are also known as the flying foxes. They belong to the class Mammalia. They feed on plant fruits and sometimes insects also.

So, the answer is ‘1-i, 2-iv, 3- ii, 4- iii ‘.

Note: The penguins are endangered animals and need protection. Environmental changes have led to some species getting extinct. Same is the case, with the Carcharodon species which have gone extinct.
