Yes, 1/2 inch supply to fill boiler will work fine. Piping going to baseboard heaters needs to be sized properly. 1/2 inch piping to baseboard heaters not recommended. Most hot water baseboard heaters piped with 3/4 pipe.
Yes. You might want to check to see what recommended temperature is for water entering the baseboard units and insure the water heater will meet that. Something else to consider is that there will need to be a pump in the water circuit to circulate the water. A tank type water heater would also work to store hot water until needed by the baseboard units in an instance where heat might be generated at a time not needed by the baseboard units.
The cold water supply enters the tank at the bottom near the burner. Heat rises, as does hot water. The hot water supply is piped out from the top.

Hurricanes are fueled by warm, very moist air. The only thing that can supply sufficient moisture is warm ocean water in and near the tropics.
If it is a hot water system and not steam, once it is properly filled & bled of air no more water should be needed unless there is a leak. Regardless of whether it is steam or hot water it is a Boiler not a furnace.
there would need to be a sufficient supply of water, an atmosphere and a gravitational pull to start with.
The plants that live in the lake have plenty of water, as long as there is sufficient rainfall to keep the lake full. They will thrive with a plentiful supply of water.
plant hormones, sufficient sunlight, water supply through soil and other environmental factors makes a plant to grow
