Nitrogen
Hydrogen
Chlorine
Phosphorus
Answer is Right!
Answer is Wrong!
The correct answer is (c). Chlorine is not present in fertilizers.
Nitrogen, hydrogen, and phosphorus are the three main elements that plants need to grow. Nitrogen is essential for the production of proteins and nucleic acids. Hydrogen is a component of water, which is necessary for all plant life. Phosphorus is essential for the production of ATP, which is the energy currency of the cell.
Chlorine is not essential for plant growth, but it can be beneficial in small amounts. Chloride ions help to regulate the water balance of plants and can also help to improve the uptake of other nutrients. However, too much chlorine can be harmful to plants.
In conclusion, the element not present in fertilizers is chlorine.
