Which of the following describes the calculation for net primary productivity? Adding primary and secondary productivity Multiplying gross primary productivity by cellular respiration Subtracting macronutrients from micronutrients Subtracting cellular respiration from gross primary productivity

Net primary productivity is ________.the amount of detritus produced by an ecosystemthe biomass of producers minus that of consumersthe total biomass of an entire ecosystemthe energy used by plants to make biomass after respirationthe amount of energy consumers derive from producers

Net primary productivity is the primary productivity of an ecosystem, after subtracting energy lost inGroup of answer choicesdead plant tissues.inefficiencies of photosynthesis.inedible plant tissues.respiration by primary producers.respiration by primary consumers.

Ecologists measure the net primary productivity of two different locations within a wetland ecosystem and determine that location #1 has a net primary productivity of 1,350 kcal/m2/yr and location #2 has a net primary productivity of 1,025 kcal/m2/yr.If location #1 experienced respiration loss of 25%, what was the gross primary productivity of that location over the period of time the data were collected?

The net annual primary productivity of a particular wetland ecosystem is found to be 5,000 kcal/m2/yr. If respiration by the aquatic producers is 11,000 kcal/m2/yr, what is the gross annual primary productivity for this ecosystem, in kcal/m2/yr? 5,000 kcal/m2/yr 6,000 kcal/m2/yr 16,000 kcal/m2/yr 22,000 kcal/m2/yr

Annual net primary productivity of whole biosphere is approximately
