Phytometer
Infiltrometer
Water-budget equation is —
∑Inflow−∑Outflow=ΔS
∑Outflow−∑Inflow=ΔS
∑Inflow×∑Outflow=ΔS
∑Inflow+∑Outflow=ΔS

(a)
Hydrometry refers to the description of oceans and rivers.
True
False
Transpiration is the process of loss of water through leaves of plants.
True
False
Assertion–Reason: Assertion (A): Evapo-transpiration combines both evaporation and transpiration. Reason (R): It occurs simultaneously from water surface and vegetation. Choose the correct option.
A & R true, R explains A
A & R true, R not explanation
A true, R false
A false, R true
