Primary production is defined as the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis . It is expressed in term of
(a) Weight `(g^(-2))` (b) Weight `(g^(-2)yr^(-1))`
(c) Energy (kcal `m^(-2)`) d. Energy (kcal `m^(-2)yr^(-1)`)

The amount of biomass or organic matter produced per unit area over a time period by the plants during photosynthesis is called

Identify the correct match . 1. Stratification : Vertical distribution of different species occupying different levels . 2. Secondary productivity : Amount of biomass or organic matter produced per unit area over a time period by plant during photosynthesis . 3. Primary productivity : Rate of formation of new organic matter by consumers . 4 Decomposition : Break down complex organic matter into inorganic substances like carbon dioxide , water and nutrients
