If the sun were to be extinguised right now, just about every living thing would die.
no you need the sunlight for vit d the gives you that. that is why you need the sunlight
Yes because they survive on plant, not human.
The flower that could survive the longest without water or sunlight would be a cactus. Now, you agreed to exotic gifts! Cacti have interesting looking shapes. You could get him a weird looking cactus. That would be funny, exotic and it would survive!
No, plants cannot survive without sunlight, herbivores cannot survive without plants, and I don't think carnivores and omnivores can survive without herbivores. Besides, they would all freeze to death within a few days anyway.
no they could not survive
Not at this point in our existence. Back when there weren't very many humans, we could survive by being hunter-gatherers and not farmers. But now the there are so many people on the planet, we must have arable land to farm.
It depends upon the illness of the human. Humans have great survival instinct and this cause them to survive for thousands of generation. However some illnesses and diseases also could threatened humans good health, eh.
Eating dirt is not a sufficient source of nutrients for humans. With water you could survive three weeks. Without water you could survive three days.
The sun produces heat and light. Without both of these most things on Earth could not live. Sunlight helps our plants grow. Bacteria, Protozoa, ect. survive by using energy from using sunlight.
