Question | Answer |
Ecological Niche | Manner in which organisms make use of resources and are influenced by the conditions of their habitat |
Habitat | Type of environment in which an organism lives |
Physical Adaptations | Genetically inherited characteristics that enable a give organism to survive and reproduce using a given niche |
Niche partitioning | The divisions of niches such as to cut down on competition |
Competition | Antagonistic struggle for a resource.
Always produces nothing but loses. |
The competitive exclusion principle (Gause's Principle) | No two species can use the same niche at the same time and place, one to the other or both will be out competed. |
Interspecific competition | Between different species |
Intraspecific competition | Within a species

S-shaped Curve | Logistic Growth- relationship to supply
Lag, accelerate, decelerate, equilibrium, carrying capacity is dotted line |
J-shaped Curve | Exponential growth rate- at a fixed rate per time period
1) lag, accelerate
2)Lag, accelerate, maximum stationary phase, crash phase, carrying capacity is dotted line |
What inevitably happens to populations that undergo a prolonged j-shaped growth? | The population overshoots their carrying capacity and crashes |
