Why is the rate of breathing in aquatic organisms much faster than in terrestrial organisms?
Terrestrial organisms have more oxygen than the aquatic ones because the terrestrial organisms are in direct contact with oxygen for respiration but the aquatic organisms respire within the water habitat with the oxygen dissolved in the water. Level of oxygen is high in the atmosphere and low in the water. Hence, the rate of breathing in aquatic organisms much faster than the terrestrial organisms and in order to obtain the required energy the aquatic organisms need to work hard.
You are given kerosene, turpentine and water. In which of these does the light travel fastest? Use the information given in Table 10.3.
