Biotic and Abiotic Factors in Earth's Complex Systems

The video explores Earth as a system, focusing on biotic (living) and abiotic (non-living) factors. It explains how these factors interact within systems, using examples like gut bacteria and antibiotics. The video also introduces Earth's spheres: atmosphere, biosphere, hydrosphere, and geosphere, describing their roles and interactions.

• Temperature

• Soil

What is the primary function of antibiotics in the human body?

• Soil

• Bacteria

• Plants

What is the atmosphere primarily composed of?

• Water

• Rocks
