the nitrogen cycle

Explanation:

1. Nitrogen makes up ~75% (3/4) of the Earth's atmosphere.
2. Nitrogen is one of the common elements essential for life.
3. Most plants take nitrogen from the soil and water in their growing environment.
4. All plants and animals require nitrogen to produce amino acids, which build proteins.

Answer:

1. (Top middle box, "is one of the"): elements
2. (Top right box, "makes up over 3/4 of the"): atmosphere
3. (Left boxes, "Is obtained by most plants from the"): soil; water
4. (Middle box below "common"): most
5. (Boxes below "and all"): plants; animals
6. (Bottom boxes, "need it to make"): amino acids; proteins

Filled map flow:

• Nitrogen → is one of the elements → common most → and all plants and animals → need it to make amino acids and proteins
• Nitrogen → Is obtained by most plants from the soil and water (In which they grow)
• Nitrogen → makes up over 3/4 of the atmosphere
