Biotic And Abiotic Factors In Earth's Complex System

The video discusses viewing 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 then introduces Earth's spheres: atmosphere, biosphere, hydrosphere, and geosphere, describing their components and significance.

Which of the following is an example of a biotic factor?

• Air pressure

• Temperature

• Gut bacteria

• Soil

What is the primary function of antibiotics in relation to biotic factors?

• To increase air pressure

• To promote the growth of bacteria

• To eliminate non-living factors

• To combat harmful bacteria

• Plants

• Soil

• Bacteria

• Animals

What is the atmosphere primarily composed of?

• Living organisms

Which sphere includes all living organisms on Earth?

• Hydrosphere

• Geosphere

• Biosphere

• Atmosphere

What does the hydrosphere encompass?

• All rocks and soil

• All water on and below Earth's surface
