All life-forms on Earth require nourishment, liquid water, and shelter.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -All of the living things that we know of need food and water in order to stay alive. Although different animals and plants might survive better in different places, such as deer living in forests and whales living in the ocean, they all need food and water to survive.

Detailed explanation-2: -All life forms require certain core chemical elements needed for biochemical functioning. These include carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur-the elemental macronutrients for all organisms-often represented by the acronym CHNOPS.

Detailed explanation-3: -Liquid water is an essential requirement for life on Earth because it functions as a solvent. It is capable of dissolving substances and enabling key chemical reactions in animal, plant and microbial cells.

Detailed explanation-4: -Water is essential for all life processes as it forms the major solvent in the body. It helps in transportation of substances in the body, carrying out metabolic reactions, maintaining the body temperature and many other such activities.

Detailed explanation-5: -Life is believed to have originated in sea water (also known as earth’s primordial soup) because sea water contained all the essential elements that were required for the origin of first life. Secondly, at the time of origin of life, the ozone layer was not formed, so terrestrial origin of life was not feasible.

Detailed explanation-6: -All living organisms are predominantly made of water: human beings about 60%, fish about 80%, plants between 80% and 90%. Water is necessary for all chemical reactions that occur in living cells-(it) is essential for food production and all living ecosystems."

Detailed explanation-7: -Life as we know it requires biogenic elements, a source of energy, liquid water, and a suitable, reasonably stable environment for evolution to take place.
