This is why they atomic number 18 called producers.All organisms, including you, guess on plants for food. The manner plant use to produce food is called photosynthesis. Photosynthesis is a chemic reaction and it can be indite down as a word equation: Carbon Dioxide + w ater (Light energy) = Glucose + group O reactants prducts ( raw materials ) RATE OF PHOTOSYNTHESIS: The rate of photosynthesis is how fast it is happening. We can often pecker this by finding out how much glucose or O2 is produced in a certain time.

Background information: The rate of photosynthesis is affected by a number of factors including light levels, temperature, handiness of water and availability of nutrients. If the conditions that the plant get hold ofs are improved the rate of photosynthesis should increase. the upper limit rate of photosynthesis entrust be constrained by a l imiting factor. This factor will prevent the! rate of photosynthesis from climb above a certain level even if other conditions needed for photosynthesis are improved. This limiting factor will match the maximum practicable rate of the photosynthesis reaction. The fact that all plants need light in hallow to photosynthesise has...
