If calcium levels within a man’s blood drop too low it can result in twitching, depression, coma, or even death. which characteristic of life is the man being affected by?

The characteristic of life that the man is being affected by is that living things require energy. So, if a person has very low levels of calcium, that means that the person doesn't have enough energy at all to maintain everyday bodily functions such as even being alive. If there is no energy in a human, he will ultimately die, so make sure to have enough calcium in your body!
