  4. The soil supplies it with raw materials rather than with foodПравильный ответ
  5. It breaks down dead material in the soil for food

Объяснение

A plant assembles sugar for itself from simple raw materials, and the leaves are where that assembly happens, so nothing outside the plant has to hand it any food. What the soil contributes is water and dissolved ions, which serve as raw materials for that assembly and for growth rather than as food, so absorbing ready-made food through the roots is not a route open to a plant at all.
