Answer:
The four different types of organic molecules in living organisms are carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are composed of carbon, hydrogen, and oxygen atoms and are a source of energy for the body. Lipids are composed of carbon, hydrogen, and oxygen atoms and are important for energy storage, insulation, and cell membrane structure. Proteins are composed of amino acids and are involved in various biological functions, such as enzyme catalysis, muscle contraction, and immune response. Nucleic acids are composed of nucleotides and store genetic information. All four types of organic molecules are essential for life and work together to maintain biological processes.
