Practice objective / multiple choice question 45 from the 2022 Waec Model Questions Vol1 Biology examination.
A typical non‑desert mammal loses water each day as follows: 0.5 L via urine, 0.3 L via nasal evaporation, and the remaining loss (through skin, respiration, etc.) accounts for the rest of a total loss of 2.5 L per day. A desert‑adapted mammal reduces urine loss by a factor of 5 and reduces nasal evaporative loss by 80 % compared with the non‑desert species, while all other losses remain unchanged. What is the total daily water loss of the desert‑adapted mammal (in litres, to two decimal places)?
