Why do humans suffocate at night when the plants around them cannot photosynthesis?

Answer 1

your question is odd, because most people don't sleep with plants around them to begin with

however if I had to answer this for a million dollars I would say that as through photosynthesis plants produce oxygen, lack of photosynthesis would mean a lack of oxygen where the person is sleeping, and I suppose under certain conditions, there would be too low levels of oxygen and the person could not breath

it makes some sense, but then not really, it would have to be in an airtight room or outer space so no oxygen could enter the room and there would have to be little or no oxygen in the room to begin with

hope this helps

Answer 2

Humans suffocate at night because they continue to consume oxygen and produce carbon dioxide through respiration, even when plants are not photosynthesizing. The oxygen we breathe in is used for cellular respiration to produce energy, and the carbon dioxide produced is exhaled into the environment. Plants are not the only source of oxygen in the environment, as oxygen is also produced by other organisms and processes.
