Guide Questions:

1. What are the Earth's subsystems? (Briefly describe each)

2. How do subsystems interact with each other? Give examples.

3. Why does the biosphere appear to be dependent on the other subsystems?

Biosphere: Includes all living organisms and ecosystems on Earth.
Atmosphere: The air surrounding Earth that contains gases like CO2.
Hydrosphere: Includes all water on Earth, such as oceans, rivers, and lakes.
Geosphere: Earth's solid parts, like rocks and soil.

Interactions: These subsystems interact through processes like photosynthesis (plants taking in CO2 and releasing oxygen) and carbon storage in plants and soil.

Dependence: The biosphere relies on the other subsystems for resources like carbon dioxide, water, and nutrients for growth and survival.
