GENERAL KNOWLEDGE

Detailed explanation-1: -1: Carbon is present in all life: All living things contain carbon in some form, and carbon is the primary component of macromolecules, including proteins, lipids, nucleic acids, and carbohydrates.

Detailed explanation-2: -Carbon is found in all living things. Carbon atoms move constantly through living organisms, the oceans, the atmosphere, and the Earth’s crust in what is known as the carbon cycle.

Detailed explanation-3: -Life on earth would not be possible without carbon. This is in part due to carbon’s ability to readily form bonds with other atoms, giving flexibility to the form and function that biomolecules can take, such as DNA and RNA, which are essential for the defining characteristics of life: growth and replication.

Detailed explanation-4: -Carbon dioxide (CO2) in the air or dissolved in water is the source of carbon found in living stuff. Through the process of photosynthesis, which converts carbon dioxide and water into simple carbohydrates, algae and terrestrial green plants (producers) are the primary agents of carbon dioxide fixation.

Detailed explanation-5: -Carbon: Carbon is the foundational element for all life on Earth. It’s capacity to form four bonds makes possible an almost limitless variety of compounds. Hydrocarbons contain only carbon and hydrogen. Derivatives of Hydrocarbons add other elements to carbon and hydrogen.
