The oxygen that plants make is taken up by humans. The humans take the oxygen and transform it into carbon dioxide. When the humans do this then the plants take it and change it back into oxygen. This is a never-ending cycle, without plants, humans and animals would die out, without humans and animals, plants would die out.
You should always check for pipes by hand, many pipes are PVC and will not show up on a metal detector.

Detector rails generate redstone energy (for a redstone wire or other contraption) when a minecart is on them. You can make a simple minecart accelerator by placing rails like so: [minecart rail][detector rail][powered rail][powered rail][detector rail][minecart rail]
Food keeps humans alive and helps to make the body stronger against diseases. Without food humans starve to death.

Humans themselves do not use photosynthesis, but because humans depend on plants, as well as other animals that eat plants, in order to live, no, humans could not live without photosynthesis. Unless plants had another way to make food for themselves, humans could not live without photosynthesis.
