How is a niche like a profession in ecological terms

The niche is similar to a profession since it is a specific role in the ecosystem. For instance, some organisms perform certain tasks in their environment, as plants release the product of oxygen during the process of photosynthesis. Decomposers have one, specific job in their ecosystem, which is to decompose dead material. Hope this helps! :)
