9. Niche
Competition
If two species try to share the same niche in the same habitat, they will compete for resources

10. Niche Competitive exclusion
The extinction of a population due to direct competition with another species for a resource

11. Niche Realized niche Fundamental niche
The actual role that the organism filling
Fundamental niche
Any of the roles that an organism can fill

13. Niche Niche Diversity The number of different niches in an ecosystem
Depends on type of biome

14. Niche Predator Keystone Predator Prey
An organism that actively hunts other organisms
Keystone Predator
A predator that promotes a great niche diversity in its habitat
Prey
The organism that is hunted

15. The sea otter Enhydra lutris can be considered a keystone predator because its voracious feeding on herbivorous sea urchins allows kelps to flourish along the rocky coast, along with an entire ecosystem associated with these large marine plants.

26. Fundamental vs. realized niche
Chthalamus barnacles can live in both deep and shallow intertidal zones (its fundamental niche).

Competition from Balanus forces Chthalamus to occupy a smaller realized niche on higher, drier habitat.
