Q15. Marsh tit birds were fed at uniform vs highly unpredictable times, and seed hoarding and body mass changes were measured. Mark the correct statement.
a Hoarding is directly and fat storage is inversely proportional to variability in food supply. b Birds prefer to store the extra energetic buffer as fat when there is scarcity of food. c It is likely that the storage of food as fat is energetically more demanding than hoarding. d The birds may be adopting a strategy of reduction in energy requirements through prolonged fat-storing torpor during times of reduced food resource availability.
