The carbon cycle vs. nitrogen cycle

  • Both cycles get affected when humans burn forests or fossil fuels, leading to a rise in oxides in the atmosphere.
  • Deforestation and agriculture are also major influences in both cycles, as they speed up decomposition which releases more oxides.

Real-World Example: Consider how using your car for daily commute contributes to combustion of fossil fuels, releasing more CO2 into the atmosphere.

The role of respiration & nitrification

  • In the carbon cycle, animals and plants release carbon dioxide (CO2) into the atmosphere through respiration.
  • In the nitrogen cycle, nitrogen oxides (NOx) get released into soil water via a process called nitrificatio

Real-World Example: Picture this like your daily routine. You eat (akin to combustion), breathe out CO2 (similar to respiration), and your waste products eventually reach the soil (similar to nitrification).

Global warming & acidification

  • Both carbon dioxide and nitrogen oxides contribute to global warming. However, CO2 is a more significant contributor.
  • Both types of oxides can lead to the acidification of water and aquatic bodies.
  • Nitrogen oxides, specifically, may also cause acid deposition and acidify soils.

Real-World Example: Think about how pouring vinegar (an acid) in your fish tank (an aquatic system) might disturb the fish (life in the ecosystem). That's a simplified version of what acidification does to ecosystems!
