Choose the correct statements.
I. Productivity is expressed in gm⁻² yr⁻¹ or (kcal m⁻²) yr⁻¹ II. The amount of biomass or organic matter produced per unit area over a time period in plants during photosynthesis is called primary production III. Primary production is expressed in terms of weight (g⁻²) or energy (kcal m⁻²) IV. Sugarcane has more efficiency to trap sunlight, so they accumulate more primary productivity
Answer: (B)
Solution
Statement I correctly gives the units of productivity, and statement IV is correct since sugarcane, being a C₄ plant, has superior photosynthetic efficiency and therefore higher primary
