Key Concepts

Fundamental vs. Realized Niche

The fundamental niche represents the full range of environmental conditions and resources an organism could theoretically use in the absence of limiting factors such as competition and predation. In contrast, the realized niche is the actual set of conditions and resources that an organism utilizes in nature, shaped by both biotic interactions and environmental constraints.

Ecological Niche

An ecological niche refers to the role and position an organism occupies in its environment, including its interactions with both living (biotic) and non-living (abiotic) components. It encompasses all the conditions, resources, and interactions necessary for the survival, growth, and reproduction of the species, effectively defining its 'profession' within the ecosystem.
