Lesson 3 - The Carbon Cycle and Soil

You will expand your understanding of the carbon cycle by digging deeper into the soil and investigate how carbon cycles through plants and how the complex soil ecosystem functions in healthy soils.

You will create a ‘mini’ carbon cycle diagram that represents the carbon cycle in healthy soil and explore how soil fungi play a critical role in plant growth and complete a three-level guide to aid your text comprehension.

You will then apply an Earth System Science approach to analyse soil degradation issues using the interactions between the four Earth spheres — the Geosphere, Hydrosphere, Atmosphere and Biosphere.
