Question

Is potential and fundamental niche the same. pls explain and what is a realised niche?

Answer 1

Potential niche - The maximum possible distribution of a species in the environment.

Fundamental Niche - The fundamental niche of a species includes the total range of environmental conditions that are suitable for existence without the influence of interspecific competition or predation from other species.

The realized niche describes that part of the fundamental niche actually occupied by the species.

Answer 2

Potential and Fundamental niche are different look at the definitions below:

Potential niche: The maximum possible distribution of a species in the environment.

Fundamental niche: All the resources that a species could possibly use in its environment.

Realized niche : That portion of a fundamental niche actually occupied by a species, which results from the sharing of resources in a given ecosystem.

Answer 3

In ecology, a niche is a term describing the relational position of a species or population in an ecosystem. More formally, the niche includes how a population responds to the abundance of its resources and enemies (e. g., by growing when resources are abundant, and predators, parasites and pathogens are scarce) and how it affects those same factors (e.g., by reducing the abundance of resources through consumption and contributing to the population growth of enemies by falling prey to them). The abiotic or physical environment is part of the niche because it influences how populations affect, and are affected by, resources and enemies.

The description of a niche may include descriptions of the organism's life history, habitat, and place in the food chain. According to the competitive exclusion principle, no two species can occupy the same niche in the same environment for a long time.
