Detailed explanation-1: -primary productivity, in ecology, the rate at which energy is converted to organic substances by photosynthetic producers (photoautotrophs), which obtain energy and nutrients by harnessing sunlight, and chemosynthetic producers (chemoautotrophs), which obtain chemical energy through oxidation.
Detailed explanation-2: -Thus, the correct answer is ‘Primary productivity depends upon the plant species inhabiting a particular area. ‘
Detailed explanation-3: -What is Primary Productivity? 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.
Detailed explanation-4: -There are two aspects of primary productivity: Gross primary productivity – The total amount of energy produced in an ecosystem. Net primary productivity – The amount of energy used by the producer for respiration.
