Question

С Write short answers. 1. Why do animals need to take in oxygen? 2. Why do animals need to move? 3. What is the difference in the way a tadpole and a frog breathe? 4. What are the characteristic features of teeth in herbivores? 5. Why do some animals migrate?​

Answer 1

Answer:

Oxygen burns the food within their bodies and releases energy for various activities and thus it helps animal to be alive. to use it in respiration!             Q.2  ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms. Q.3 Tadpoles are aquatic and gill-breathing while frogs are lung breathing. Moreover adult frogs on land, can also exchange respiratory gases through moist skin. Q.4  ridged molars and jaws capable of moving sideways. Both of these traits help herbivores to grind their food more effectively. Most herbivores are missing canines entirely, and those that do possess them usually have very small or reduced canines that are not very important for chewing food. Q.5  populations of animals to move from an area where food resources are scarce to an area of more abundance.

Answer 2

Answer:

the answer is as follows:-

Explanation:

1. Animals need oxygen because Oxygen burns the food within their bodies and releases energy for various activities.

2.Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators.

3.When they are tadpoles, frogs have gills to breathe water, a long tail, and no legs.  Adult frogs have lungs to breathe air, no tail, and four legs.

4.herbivores feature ridged molars and jaws capable of moving sideways. Both of these traits help herbivores to grind their food more effectively. Most herbivores are missing canines entirely, and those that do possess them usually have very small or reduced canines that are not very important for chewing food.

5.Animal migration is the large-scale movement of a species from one place to another. Most species migrate during specific seasons, in search of food or water, or for mating reasons.
