Niches and Community Interactions

4.2 Ecosystems and CommunitiesBy: Deborah Lamoreaux The ability of an organism to survive and reproduce under circumstances that differ from there optimal conditions.

4.2 Tolerance:4.2Why does and organism experience stress?When the temperature extends further than the organisms optical range the organisms will become stressed.4.2Habitat:A general place were an organism lives.4.2Niche:Not only what the organism does, but also how it interacts with the biotic and abiotic factors.

Some of 4.2By: Abigail SaxtonCompetitionCompetition When organisms attempt to use the same limited ecological resources in the same place at the same time.ForestPlant roots compete for water and nutrients in the soil.Animals (beetles)Compete for resources such as FoodMatesA place to liveRaise their young

Intraspecific & Interspecific Competition Intraspecific This occurs between members of the same species. Interspecific Different Species

Competition Exclusion Principle Competition Exclusion PrincipleStates that no two species can occupy exactly the same niche in the exact same habitat at the exact same time.If two species were to attempt to occupy the same niche, one species will be better at competing for limited resources.*Which would eventually exclude the species*

*Niche: The status of an organism within the environment and community.

Symbiosis- Living together of organisms

3 classes: Mutualisms; Parasitism; Commensalism

4.2 Continued

Mutualism-Relationship between two species that the both benefit

Ex: Clownfish and the sea anemone

4.2

Parasitism-One organism lives on/in another organism and harms that organisms

Ex: Tapeworms, Fleas, Ticks & Lice

Examples Of A ParasitismVirusesbacteria fleasand fungi are all classified as a parasitism.

What Is A Commensalism?A Commensalism is a relationship in which one organism benefits and the other is neither helped or harmed.

Examples Of A CommensalismBarnaclesRemora sharksAnd a crab that makes its home in an oysters shell.
