Question 11

The external factors would include the availability of sunlight, temperature,

CO_{2}

concentration and water. As a plant photosynthesises, all these factors will simultaneously affect its rate. Hence, though several factors interact and simultaneously affect photosynthesis or

CO_{2}

fixation, usually one factor is the major cause or is the one that limits the rate. Hence, at any point the rate will be determined by the factor available at sub-optimal levels. Ruel that below the option level. When several factors affect any [bio] chemical process, Blackman's (1905) Law of Limiting Factors comes into effect. This states the following: If a chemical process is affected by more than one factor, then its rate will be determined by the factor which is nearest to its minima
