How much Ice @ 0°C must be mixed with 50.0g of water @ 75.0°C to give a final water temperature of 20°C?

How do I state 2nd law of thermodynamics for an open system?

Ecosystems are open systems, they receive solar energy and other materials from outside the ecosystem and migration of animals is also witnessed.

I read Physics uptil class XII and have done a bit of research on google books and have come across these three books:

1.Towards a Thermodynamic Theory for Ecological Systems, pg-41

2.Thermodynamics of Non-Equilibrium Processes for Chemists, pg-9

3.Ecosystem Ecology, pg-35

P.S. I couldn't come up with anything statement.
