Question

Primary productivity is measured in terms of diurnal method

Answer 1

Answer:Primary productivity is the process by which organisms make their own food from inorganic sources. The majority of primary producers are terrestrial plants and microbial life, such as algae. These organisms are known as autotrophs, since they can use inorganic substrates and solar energy to carry out metabolic processes and build cellular material. Primary productivity due to photosynthesis is commonly measured by quantifying oxygen production or CO2 assimilation.
