match the nutrient to its deficiency symptom.
new growth is distorted or dies
yellowing between veins on older leaves
leaf edges appear scorched or brown
young leaves turn yellow but veins stay green
calcium
nitrogen
potassium
iron

Explanation:

• Calcium deficiency causes new growth to be distorted or die as it is crucial for cell wall structure and growth processes in new plant tissues.
• Iron deficiency leads to young leaves turning yellow while veins stay green (interveinal chlorosis) as iron is involved in chlorophyll synthesis and is less mobile in the plant, so deficiency shows first in new growth.
• Potassium deficiency results in leaf edges appearing scorched or brown as potassium is important for stomatal regulation, enzyme activation, and maintaining cell turgor; its deficiency affects the edges of leaves first.
• Nitrogen deficiency causes yellowing between veins on older leaves as nitrogen is a mobile nutrient; when deficient, the plant translocates nitrogen from older leaves to newer, more actively growing tissues.

Answer:

• New growth is distorted or dies - Calcium
• Yellowing between veins on older leaves - Nitrogen
• Leaf edges appear scorched or brown - Potassium
• Young leaves turn yellow but veins stay green - Iron
