Greenhouse economics

• Why are limiting factors important in economics?

  because of enhancing the conditions in greenhouses to gain the maximum rate of photosynthesis while still maintaining profit
• Why do greenhouses trap heat from the sun to maximise photosynthesis?

  So temperature isn't a limiting factor
• Why do greenhouses use a heater in winter to maximise photosynthesis?

  So temperature isn't a limiting factor
• Why do greenhouses open vents in the summer to maximise photosynthesis?

  So temperature doesn't get too hot and denature enzymes
• Why greenhouses are transparent so light can enter to maximise photosynthesis?

  So light isn't a limiting factor
• Why do greenhouses add artificial light for evenings/winter to maximise photosynthesis?

  so light isn't a limiting factor
• Why do greenhouses use paraffin heaters to produce carbon dioxide to maximise photosynthesis?

  So carbon dioxide isn't a limiting factor
