Why are light compensation points lower for shade plants?

#Unit 6. System Physiology – Plant
  1. Respiration rate in shaded plants are higher
  2. because only  a little photosynthesis is necessary to bring the net rates of CO2 exchange to negative
  3. this is because respiration rates in shade plants are very low
  4. because shaded plants ability to achieve negative CO2 uptake rates at lower PPFD values than sun plants
