Detailed explanation-1: -A compound found mainly in living things is known as an organic compound. Organic compounds make up the cells and other structures of organisms and carry out life processes. Carbon is the main element in organic compounds, so carbon is essential to life on Earth. Without carbon, life as we know it could not exist.
Detailed explanation-2: -This means that all organic compounds have in common the presence of carbon atoms and hydrogen atoms. In addition, different organic compounds may contain oxygen, nitrogen, phosphorous, and other elements.
Detailed explanation-3: -Organic molecules are the molecules which exist in all living things. They are life’s building blocks. All things are formed from these organic molecules. There are four categories of organic molecules: Carbohydrates, lipids, proteins and nucleic acids.
Detailed explanation-4: -Hydrocarbons are organic molecules consisting entirely of carbon and hydrogen, such as methane (CH4) described above.
