In the carbon cycle, what role do forests primarily serve?

Forests primarily serve as significant carbon sinks in the carbon cycle, which means they have the ability to absorb and store carbon dioxide from the atmosphere. Through the process of photosynthesis, trees and plants take in carbon dioxide, using it to produce energy and grow, thus effectively reducing greenhouse gas concentrations. This function is crucial in mitigating climate change, as forests can sequester large amounts of carbon over time in their biomass and soil. By storing carbon, forests help regulate the global carbon cycle, making them vital for maintaining ecological balance and supporting life on Earth.
