Which of the following is considered as the main ecological service?

Step-by-step solution

Ecosystem services are the direct and indirect benefits that humans and other living organisms obtain from natural ecosystems. While ecosystems provide numerous vital services such as waste decomposition, purification of water and air, and genetic resources, the most fundamental and main ecological service is the fixation of atmospheric CO₂ and the release of O₂ . This process, driven by photosynthesis in primary producers (plants, algae, and some bacteria), forms the basis of the entire food web by converting sola
