Outline the possible reasons why a large share of the light energy that strikes plant leaves is not changed into chemical energy.
The PE of most crops lies between 1% and 4%. Sugar cane, an important crop for food production and for the production of biofuel, has a PE of 7% to 8%. Suggest the advantages of growing crops with high PE for food production or for biofuel production.
Fertilisers containing nitrate are added to improve or maintain yield of crops such as sugar cane. Name two organic compounds containing nitrogen that are made by plants and state one function of each in plant growth.
