Which of the following elements is required in large amounts by plants

Phosphorus is the element required in large amounts by plants. It is an essential macronutrient that plays a critical role in many biological processes, such as photosynthesis, respiration, and energy storage and transfer. Phosphorus is a component of DNA, RNA, and ATP, which are crucial molecules for plant growth and reproduction. Without adequate phosphorus, plants can develop stunted growth, weak roots, and have difficulty producing flowers and fruits. Therefore, phosphorus is an essential nutrient for plants to survive and thrive.
