Unit 1: Intro to Ecosystems Flashcards
Competition
When individuals struggle to get a limited resource that is shared with others.
Competitve exclusion principle
Two species competing for the same limited resource can’t coexist. One species will do better than the other when they have the same ideal conditions.
Resource partioning
2 species dividing dividing resources to avoid competion over a shared resource.
Symbiotic relationships
Two species closely associated with eachother.
Predator
An animal that consumes another, its prey.
Prey
The animal a predator kills and consumes.
Temporal Resource Partioning
2 species in the same area using the same resources at different times.
Spatial Resource Partioning
2 species reduce competition by using different habitats.
Morphological Resource Partioning
Natural evolution reduces competition.
