In short: While plants produce their own food through photosynthesis, they cannot create every building block of life from thin air alone. This video explains the vital partnership between solar energy and mineral nutrients.

Plants are autotrophic organisms, meaning they synthesize their own macromolecules using photosynthesis. However, to build essential components like proteins, they must extract specific elements from the soil.

A primary example is nitrogen; without this specific nutrient, plants suffer from stunted growth because they lack the raw materials required for protein synthesis.
