Answers
Answer:
1. An amphibian is a cold-blooded vertebrate animal that is born in water and breathes with gills. As the larva grows into its adult form, the animal's lungs develop the ability to breathe air, and the animal can live on land. Frogs, toads, and salamanders are all amphibians.
3. Gills are the respiratory organs in aquatic organisms such as fishes.
Lungs are the respiratory organs of many land animals such as lizards, dogs, frogs etc.
6. Trachea: A tube-like portion of the respiratory tract that connects the larynx with the bronchial parts of the lungs. Also known as windpipe.
7. Those who can fly, soar or glide easily in the air are aerial animals.They move strongly via air via powered flight abilities such as flapping wings to produce the required lift and thrust.
8. Migration, in ethology, the regular, usually seasonal, movement of all or part of an animal population to and from a given area. Familiar migrants include many birds; hoofed animals, especially in East Africa and in the Arctic tundra; bats; whales and porpoises; seals; and fishes, such as salmon.
