LIFE SCIENCE

Detailed explanation-1: -The CHNOPS elements are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. These elements are the most abundant elements found in living things. Together, the six elements of life, form large, organic molecules known as macromolecules or biomolecules.

Detailed explanation-2: -Four elements-carbon (C), oxygen (O), hydrogen (H), and nitrogen (N)-make up 96% of living matter. Most of the remaining 4% of an organism’s weight consists of phosphorus (P), sulfur (S), calcium (Ca), and potassium (K).

Detailed explanation-3: -Oxygen, silicon, iron and aluminum are the most abundant elements in the Earth’s crust, accounting for 88.1% of its mass.

Detailed explanation-4: -There are 92 naturally occurring elements, each differing from the others in the number of protons and electrons in its atoms. Living organisms, however, are made of only a small selection of these elements, four of which-carbon (C), hydrogen (H), nitrogen (N), and oxygen (O)-make up 96.5% of an organism’s weight.

Detailed explanation-5: -Major biomolecules (carbohydrates, proteins, lipids and nucleic acids) on earth are made up of carbon, hydrogen, oxygen and nitrogen.
