Ans. (i) Aquatic Eco-system: On the basis of salt content, aquatic eco-system can be divided into fresh water eco-system and marine eco-system. The California grunion stands apart from its relatives because it mates completely out of water, leaving the fertilized eggs buried in the sand to incubate until the next semilunar tide. 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. Terrestrial ecosystems are the habitats found … Terrestrial organisms breathe by using atmospheric oxygen whereas aquatic organism take oxygen dissolved in water. What are the different ways in which glucose is oxidised to provide energy in various organisms? Some water bodies like rivers and lakes were formed due to molting of glaciers. Therefore, unlike aquatic animals, terrestrial animals do not need adaptations for gaseous exchange. The two main types of aquatic ecosystems are marine ecosystem and freshwater ecosystem. Answer:-In the aquatic habitat the concentration of oxygen is good up to a certain depth only. Any help is appreciated! What advantage over an aquatic organism does a terrestrial organism have with regard to obtaining oxygen for respiration? NCERT NCERT Exemplar NCERT Fingertips Errorless Vol-1 Errorless Vol-2. What advantages over an aquatic organism does a terrestrial organism have with regard to obtaining oxygen for respiration? Oh! (i) Aquatic Eco-system: On the basis of salt content, aquatic eco-system can be divided into fresh water eco-system and marine eco-system. Since the content of O 2 in air is high, the terrestrial animals do not have to breathe faster to get more oxygen. Answer: Aquatic animals utilize the oxygen dissolved in water. This birthing shift from land to water cultivated other differences that made reptiles suitable for terrestrial instead of aquatic life. Terrestrial organism obtains oxygen for respiration from the atmosphere where the oxygen content is high, whereas, aquatic organisms obtain oxygen dissolved in the water which is very low when compared to the amount in atmosphere. Give reason. But, aquatic organisms have to breathe very quicker than terrestrial organisms, because oxygen dissolved in water is low compared to the oxygen … Hurray i have got my answer, Your email address will not be published. An organism living in a completely aquatic environment has several advantages: their body is supported inside and out, the current of water constantly bathes their cells and brings nutrients and oxygen while carrying away wastes, and rapid changes in temperature were prevented. The rate of breathing in aquatic organisms is much faster than that seen in terrestrial organisms. Terrestrial organismslive most of their life on (or in) land (like humans), some of them being aquaticfrom “birth” (many insects). 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. The California grunion, Leuresthes tenuis, may have the most curious reproductive strategy of any fish. … Flightless insects also are early terrestrial organisms. Advantage over an aquatic organism does a terrestrial organism have with regard to obtaining oxygen for respiration - 11301890 What advantage over an aquatic organism does a terrestrial organism have with regard to obtaining oxygen for respiration? Answer:-. Why is the rate of breathing in aquatic organisms much faster than in terrestrial organisms ? Aquatic organism takes in the oxygen dissolved in water which is in less percentage than the oxygen present in air. Terrestrial organisms take up oxygen from the atmosphere whereas aquatic animals obtain oxygen from water. Air contains more O2 as compared to water. Solution: Terrestrial organisms take up freely suspended oxygen from the atmosphere whereas aquatic organisms have to obtain oxygen dissolved in the surrounding water. On the other hand, terrestrial animals take oxygen directly from atmosphere, so their rate of breathing is comparatively less. Thus, a terrestrial animal has an advantage over an aquatic animal in regard to obtaining oxygen for respiration that is surrounded by an oxygen rich atmosphere from where it can take any amount of oxygen. Savannas are hot, tropical areas with temperatures averaging from 24 o C –29 o C (75 o F –84 o F) and an annual rainfall of 51–127 cm (20–50 in). What advantage over an aquatic organism does a terrestrial organism have with regard to obtaining oxygen for respiration February 20, 2019 by Amit Oxygen content in water is lesser as oxygen is not highly soluble in water while the concentration of oxygen is high in the atmosphere. Aquatic Ecosystem and Terrestrial Ecosystem! Physics. The terrestrial animals use the oxygen of air or atmosphere for breathing and respiration.

Animals and plants living in a terrestrial environment will be very different from animals and plants living in an aquatic environment. Thus, a terrestrial animal has an advantage over an aquatic animal in regard to obtaining oxygen for respiration that is surrounded by an oxygen rich atmosphere from where it can take any amount of oxygen. It is not that a terrestrial organism has an advantage over an aquatic organism and vice-versa. The matrix of water plays a vital role in the evolution of an aquatic organism.
