Which one of the following is not an accurate description of the term used?
A
An organism’s ecological niche is the way in which each individual functions within its environment; for example, the time it feeds and what it feeds on.
B
Classic experiments and mathematical models demonstrate the competitive exclusion principle, which is that two species cannot coexist on the same limiting resource if they use it in the same way.
C
Biodiversity is observable in the tropics, where 150 species of fish may feed on or shelter among the same corals.
D
Resource partitioning describes how coexistence can occur when there is differentiation between the ecological niches of different species.
Explanation: 

Detailed explanation-1: -An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces. A species’ niche includes all of its interactions with the biotic and abiotic factors of its environment.

Detailed explanation-2: -Niche is of four types namely: Habitat niche, Food niche, Reproductive niche and Physical & Chemical Niche.

Detailed explanation-3: -In ecology, the term “niche” describes the role an organism plays in a community. A species’ niche encompasses both the physical and environmental conditions it requires (like temperature or terrain) and the interactions it has with other species (like predation or competition).

Detailed explanation-4: -1. Three parts of a niche include food type, abiotic conditions, and behavior. 2. One species will be better suited to the nice and the other species will either be pushed into another niche or become extinct.
