This episode unpacks how biotic components like plants, animals, and decomposers rely on abiotic resources like air, water, and sunlight to survive. We follow the movement of nutrients as they are drawn from the ground to support organic growth, only to be returned to the earth when those organisms die.

• Survival for any biological organism requires direct interaction with non-living elements.
• Producers utilize solar energy and atmospheric carbon dioxide to synthesize food.
• Decomposition by soil organisms ensures that organic nutrients are converted back into the ground.
