How does s cell get it's 4 main elements? - Answers

Cells obtain their four main elements—carbon, hydrogen, oxygen, and nitrogen—primarily through the intake of nutrients from their environment. These elements are found in organic molecules like carbohydrates, proteins, lipids, and nucleic acids, which cells consume from their surroundings. Additionally, plants absorb carbon dioxide from the air and water from the soil, while all organisms utilize metabolic processes to incorporate these elements into cellular structures. Ultimately, the cycling of matter within ecosystems ensures the availability of these essential elements.
