1. Algae spontaneously extract carbon dioxide from the air, which they convert into the proteins, lipids, and sugars that make up the composition of their bodies.
2. Algae use energy from the sun to fuel their growth processes.
Humans only need provide water and trace minerals; the algae do the rest. It is something like a garden—you expend a certain amount of energy planting and tending for the plants, but you can completely feed yourself from that garden because the energy yield is far more than the energy input.

No. You would starve to death using such logic. You require two potatoes worth of energy to grow one potato.
Biofuel is a monument to a the success of conventionally-produced petroleum.
