"A living plant leaf is an open system that exchanges energy (sunlight and thermal flows) and matter (O2, CO2, water vapor, etc.) with the surroundings (the exterior). Even with irreversible processes (energy dissipation) we4 find that the net entropy change for the system and surroundings can decrease, ie dS < 0. Explain how this is possible in terms of dS_system and dS_surroundings and explain how the second law of thermodynamics remains valid for this case."
