1. Carbohydrates:
• Carbon Cycle: Carbohydrates are composed primarily of carbon, hydrogen, and oxygen. During photosynthesis, plants and some microorganisms take in carbon dioxide (CO2) from the atmosphere and convert it into carbohydrates, releasing oxygen (O2) as a byproduct.
2. Proteins:
• Nitrogen Cycle: Proteins are made up of amino acids, and nitrogen is a crucial component of amino acids. The nitrogen cycle involves the transformation of nitrogen compounds in the environment, making nitrogen available for plants to assimilate and incorporate into proteins.
3. Lipids (Fats):
• Carbon Cycle: Like carbohydrates, lipids contain carbon. When organisms use lipids as an energy source, they release carbon dioxide into the atmosphere through respiration.
4. Nucleic Acids (DNA and RNA):
• Phosphorus Cycle: Nucleic acids, specifically DNA and RNA, contain phosphorus in their structure. The phosphorus cycle involves the movement of phosphorus through ecosystems as it is incorporated into nucleotides and nucleic acids in living organisms.
