Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the chemical structure (orthophosphate)?Tetrahedral arrangement of four oxygen atoms around a central phosphorus atom
2. What is the primary industrial application?Key component of fertilizers essential for global agriculture
3. What is a phosphate and why is it called a tiny builder?A phosphate is a small chemical group made of one phosphorus atom and four oxygen atoms. It helps build plants, bones, and the energy inside cells.
4. Why do plants need phosphates?Plants absorb phosphates from soil and use them to grow strong roots and leaves. The phosphates become part of the plant’s cells and later move into the food we eat.

Organophosphate: Esters of phosphoric acid where organic groups replace hydroxyls, found in biological molecules and industrial chemicals.
Eutrophication: The excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.
ATP (Adenosine Triphosphate): The primary molecule for storing and transferring energy in cells, characterized by high-energy phosphate bonds.
