SOLAR SYSTEM

Detailed explanation-1: -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-2: -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-3: -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.

Detailed explanation-4: -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-5: -It is needed by all living things and every living cell to carry out life processes, such as breaking down and building up molecules, and transporting many molecules across cell membranes. The form of energy that living things need for these processes is chemical energy, and it comes from food.
