Which term describes inputs such as Fertilizer, Pesticides, and Irrigation?

• A. Physical Inputs
• B. Flood Water
• C. Expenditure
• D. Human Inputs

Answer: (D)

Inputs into farming can be natural resources or things people supply and manage. Fertilizer, pesticides and irrigation are all provided or controlled by people: fertilizers and pesticides are manufactured substances added to crops, and irrigation relies on infrastructure, pumps and careful water management. Because they involve human action, technology, and investment, they’re classified as human inputs. Flood water, by contrast, is a natural resource that occurs without human production; expenditure refers to money spent, not a resource itself; and physical inputs would cover natural elements like climate or soil, not these human-provided tools.
