Chickens reared for meat are often kept in sheds that are heated. Why does heating the sheds increase the mass of meat produced?
The chickens eat less food, so more of their food is used to make new cells
The chickens lose less energy as heat, so more energy is available for growth
The chickens drink more water, so more water is stored in their body tissues
The chickens breathe more quickly, so more oxygen reaches their body cells
