What advantage over an aquatic organism does a terrestrial organism

Terrestrial organisms take up oxygen from the atmosphere whereas aquatic animals need to utilize oxygen present in the water. Air contains more O 2 ​ as compared to water. Since the content of O 2 ​ in air is high, the terrestrial animals do not have to breathe faster to get more oxygen. Therefore, unlike aquatic animals, terrestrial animals do not have to show various adaptations for better gaseous exchange. Views: 5,935 10 m away. (a) Based on the text and data given in the above paragraph, what kind of lens must the slide projector have? (b) If v is the symbol used for image distance and u for object distance then with one reason state what will be the sign for u v ​ in the given case? (c) A slide projector has a convex lens with a focal length of 20 cm. The slide is placed upside down 21 cm from the lens. How far away should the screen be placed from the slide projector's lens so that the slide is in focus? OR (c)When a slide is placed 15 cm behind the lens in the projector, an image is formed 3 m in front of the lens. If the focal length of the lens is 14 cm, draw a ray diagram to show image formation.

Terrestrial organisms take up oxygen from the atmosphere whereas aquatic animals obtain oxygen dissolved in water. Air contains more O 2 as compared to water. Since the content of O 2 in the air is high, the terrestrial animals do not have to breathe faster to get more oxygen. Therefore, unlike aquatic animals, terrestrial animals do not need adaptations for gaseous exchange and can adapt to a relaxed mode of breathing. Q. (a) Why is diffusion insufficient to meet the oxygen requirements of large multicellular organisms like humans ? (b) What type of arrangement exists in the bodies of large animals to meet their oxygen requirements adequately ? (c) What advantage a terrestrial animal has over an aquatic animal with regard to obtaining oxygen for respiration ?

For this reason, aquatic animals breathe faster to obtain as much oxygen as possible, on the other hand, terrestrial animal does not have to breathe faster and thus spends less energy than aquatic organism.

• Air contains about 21% oxygen while water has 1% oxygen in dissolved state. • A terrestrial organism is able to get several more times oxygen than an aquatic animal and have an advantage over them. • Aquatic animal like fishes has to talk up the dissolved oxygen that is present in the water. And the amount of oxygen that is dissolved from the atmosphere to water is less compared to the concentration of the oxygen that is present in the air. Also, the solubility of the oxygen in the water varies depending on the temperature and pressure on the water surface. • Aquatic animals, therefore, have to breath very fast in order to provide their body with thee required the amount of oxygen. Some of the fishes have even developed the alternate way of breathing by coming up to the water surface and take a large gulp of air and then dive below water. • Terrestrial animals whereas are provided with an atmosphere which is rich in oxygen and they have intake and outtake of the air just depending on the difference in the pressure inside the lungs and the outside temperature. • Therefore less of their energy is used and they can utilize their food energy compared to how aquatic animals utilize their energy.
