344748 In relation to Gross primary productivity and net primary productivity of an ecosystem, which one of the following statements is correct?

344749 Statement A :
Primary production is defined as the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis.
Statement B :
A constant inputof solar energy is the basic requirement for any ecosystem to function and sustain.

344750 Read the given statements and select the correct options
I. The amount of biomass or organic matter produced per unit area over a time period in plants during photosynthesis is called primary production.
II. Gross primary productivity of an ecosystem is the rate of production of organic matter during photosynthesis.
III. Productivity is expressed in \({{\rm{gm}}^{{\rm{ - 2}}}}{\rm{y}}{{\rm{r}}^{{\rm{ - 1}}}}{\rm{or}}\,\,{\rm{(kcal}}\,{{\rm{m}}^{{\rm{ - 2}}}}{\rm{)y}}{{\rm{r}}^{{\rm{ - 1}}}}\)
IV. Net primary productivity is the available biomass for the consumption to heterotrophs

344751 Assertion :
Net primary productivity is constant in different types of ecosystems.
Reason :
It is independent of the plant species inhabiting a particular area, various environmental factors, availability of nutrients and photosynthetic capacity of plants.

344752 Which of the following ecosystems is most productive in terms of net primary production?
