BECE Science 2021 Paper

Concept:Macro-nutrients are required by plants in large amounts.Micro-nutrients are required only in trace amounts.Explanation:Plants need both macro-nutrients and micro-nutrients for healthy growth.Macro-nutrients include carbon ($\mathrm{C}$), hydrogen ($\mathrm{H}$), oxygen ($\mathrm{O}$), nitrogen ($\mathrm{N}$), phosphorus ($\mathrm{P}$), potassium ($\mathrm{K}$), calcium ($\mathrm{Ca}$), magnesium ($\mathrm{Mg}$), and sulphur ($\mathrm{S}$).Micro-nutrients include iron ($\mathrm{Fe}$), manganese ($\mathrm{Mn}$), copper ($\mathrm{Cu}$), molybdenum ($\mathrm{Mo}$), zinc ($\mathrm{Zn}$), boron ($\mathrm{B}$), chlorine ($\mathrm{Cl}$), and nickel ($\mathrm{Ni}$).Among the given options, copper, manganese, and molybdenum are micro-nutrients.Sulphur is the only macro-nutrient listed in the options.

Macro-nutrients	Micro-nutrients
Carbon ($\mathrm{C}$), Hydrogen ($\mathrm{H}$), Oxygen ($\mathrm{O}$), Nitrogen ($\mathrm{N}$), Phosphorus ($\mathrm{P}$), Potassium ($\mathrm{K}$), Calcium ($\mathrm{Ca}$), Magnesium ($\mathrm{Mg}$), Sulphur ($\mathrm{S}$)	Iron ($\mathrm{Fe}$), Manganese ($\mathrm{Mn}$), Copper ($\mathrm{Cu}$), Molybdenum ($\mathrm{Mo}$), Zinc ($\mathrm{Zn}$), Boron ($\mathrm{B}$), Chlorine ($\mathrm{Cl}$), Nickel ($\mathrm{Ni}$)

Answer:D. Sulphur
