What is the rarest key requirement for life?
“The others are carbon, hydrogen, nitrogen, oxygen and sulphur.
Without phosphorus, there would be no adenosine triphosphate (ATP), which is the molecule cells use to transfer energy.” Phosphorus is relatively rare in the universe, the rarest of the six elements required for life as we know it..
What are the four requirements for life?
It is useful to categorize the requirements for life on Earth as four items: energy, carbon, liquid water, and various other elements.
What are the functional requirements of life?
The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction. In humans, who represent the most complex form of life, there are additional requirements such as growth, differentiation, respiration, digestion, and excretion.

What is the rarest planet?
Known as GW Orionis (or GW Ori) and located about 1,300 light-years from Earth, the system is a rare example of a triple-star solar system, with two suns orbiting one another at the center, and a third star swirling around its siblings from several hundred million miles away.
What keeps a human body alive?
Oxygen. Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are especially sensitive to lack of oxygen because of their requirement for a high-and-steady production of ATP.
What are the 3 needs of life?

Will Earth be able to continue to sustain life if one of the characteristics is missing?
No earth won’t be able to sustain life if any of the major spheres is removed because the life on earth is present in the biosphere. Biosphere which is formed by the interaction of all the spheres of earth viz lithosphere, hydrosphere and atmosphere which can sustain life.

What are the requirements for the maintenance of life?
water, food, oxygen, heat, and pressure.
What do humans need the most?
The first and most basic of all needs are those to do with physical survival. This is the need for food, drink, shelter, sleep and oxygen. If a person cannot satisfy this basic survival need it dominates their interest and concern.
