Definition
Limiting factor is any factor that directly affects the rate of chemical reaction. Rate of reaction can be increased only if the value of the limiting factor is increased. #BiologyDefinitions

| Beyond Point A ⇒ light ⇒ no longer the limiting factor ⇒ since rate of photosynthesis remains constant even though light intensity increases. → either temp or concentration becomes the limiting factor | Temp. ⇒ remains constant ⇒ and concentration of env. raised to 0.13% → indicates concentration is the limiting factor in graph 1. ( is an important limiting factor since atmospheric carbon dioxide remains constant at around 0.01%) | increasing temperature ⇒ while keeping concentration constant. ⇒ temperature of surrounding area is limiting factor in graph 2. |
