The term for an organism's role in its environment is known as its niche. A niche encompasses how an organism interacts with both biotic factors, like other organisms, and abiotic factors, such as climate and resources. Understanding an organism's niche is essential for studying ecosystems, as it elucidates the relationships between species and their environment. Each organism occupies a unique niche, contributing to biodiversity and ecological balance. Changes in an organism's niche can impact community dynamics, species interactions, and ecosystem health.
