[1]

Markscheme
  1. the mixture was closer to what the bees ate naturally;
  2. the bees like the taste better/prefer sucrose;
  3. there was more lipid in the 25:1 mixture so they achieved their daily lipid/energy requirement with less mass of food;
  4. the bees eating 50:1 diet ate more to reach their daily lipid requirement;
  5. prefer the higher proportion of protein (in the 50:1)
