## What do you learn in Biogeochemistry

Biogeochemistry explores how chemical elements cycle through Earth's systems, including living organisms, rocks, water, and atmosphere. You'll study carbon, nitrogen, and phosphorus cycles, examine how microorganisms influence these processes, and investigate the impacts of human activities on global biogeochemical cycles. The course covers ecosystem dynamics, climate change, and the interconnections between biological, geological, and chemical processes on Earth.

## Is Biogeochemistry hard?

Biogeochemistry can be challenging because it combines concepts from biology, geology, and chemistry. You'll need a solid foundation in all three areas to really get it. The math isn't too crazy, but there's a lot of interconnected processes to wrap your head around. That said, if you're into environmental science or Earth systems, you'll probably find it super interesting, which makes the difficulty more manageable.
