Explanation:

All living cells require energy for various activities. This energy is available by the breakdown of simple carbohydrates either using oxygen or without using oxygen. (i) Energy in the case of higher plants and animals is obtained by  a) Breathing  b) Tissue respiration  c) Organ respiration  d) Digestion of food (ii) The graph below represents the blood lactic acid concentration of an athlete during a race of 400 m and shows a peak at point D. Lactic acid production has occurred in the athlete while running in the 400 m race. Which of the following processes explains this event?  a) Aerobic respiration  b) Anaerobic respiration c) Fermentation  d) Breathing (iii) Study the graph below that represents the amount of energy supplied with respect to the time while an athlete is running at full speed. Choose the correct combination of plots and justification provided in the following table Plot A Plot B Justification a) Aerobic Anaerobic Amount of energy is low and inconsistent in aerobic and high in anaerobic b) Aerobic Anaerobic Amount of energy is high and consistent in aerobic and low in anaerobic c) Anaerobic Aerobic Amount of energy is high and consistent in aerobic and low in anaerobic d) Anaerobic Aerobic Amount of energy is high and inconsistent in anaerobic and low in aerobic (iv) The characteristic processes observed in anaerobic respiration are  i) presence of oxygen  ii) release of carbon dioxide  iii) release of energy  iv) release of lactic acid  a) i) ,ii) only  b) i), ii), iii) only  c) ii), iii), iv) only  d) iv) only (v) Study the table below and select the row that has the incorrect information. Aerobic Anaerobic a) Location Cytoplasm Mitochondria b) End Product CO2 and H2O Ethanol and CO2 c) Amount of ATP High Low d) Oxygen Needed Not needed class-10Read more on Sarthaks.com - https://www.sarthaks.com/972018/energy-the-case-of-higher-plants-and-animals-obtained-by-breathing-tissue-respiration
