Humans do not need to expose themselves to solar radiation directly to survive. However, if there were no solar radiation at all, temperatures on Earth would quickly drop below freezing, and plants would not be able to grow. Humans would not live long under such conditions.

Without resources such as trees, minerals, water, etc. humans would not be able to create the things we have, survive, or do anything. Humans cannot survive solely on our own.
no because tree give us oxygen which we need and the absorb carbon dioxide which is bad for humans.
Without a stomach, manatees (and humans) would not be able to digest food and would soon starve to death!
Of course. You just need to find a planet with atmosphere breathable for humans, tolerable gravity, with temperatures humans can survive, and without too much solar radiation. It also needs to have plant and animal life humans can eat, or needs to be able to support plants and animals from Earth. This is when you don't consider terraforming, of course. With terraforming, the major concerns are planetary gravity, distance from the star, the state of the star, and general chemical composition of the planet.
Air has oxygen in it, without which we will not be able to survive. There is also some carbon dioxide in the air which is taken by the plants and give off oxygen in return. Oxygen is very important for life.
Yes, oxygen is the most important gas in the air for humans as it is essential for cellular respiration, which provides cells with the energy they need to function. Without oxygen, humans would not be able to survive.
The Sun is the most important member of our solar system with out it the earth would not be able to survive.
When you are no longer able to survive or function efficiently without the thing in question.
Animals can survive by their gills and they have oxygen in their gills. Humans have been able to survive in the ocean only because of aqua lung and also submersibles also known as submarine's
Spiders can survive for several weeks without water, as they are able to get moisture from their prey and the environment.
Oxygen is the gas in the atmosphere that is essential for human life. Our bodies use oxygen to generate energy through the process of respiration. Without oxygen, humans would not be able to survive.
