Interactions of Living ThingsEcology Part II Interactions of Living Things
What is an ecological niche?The place where an organism lives and that provides the things the organism needs is called its habitat.
What is an ecological niche?An organism's particular role, or how it makes its living, is called its niche.
Interactions Among Living Things 22.3
Three major types of interactionscompetition predation symbiosis.
How does competition relate to ecosystems?
Competition is the struggle between organisms to survive in a habitat with limited resources.
Explain how predator-prey relationships affect populations in an ecosystem.
Predation is an interaction in which one organism kills and eats another organism.Prey Predator
Predators have adaptations that help them catch and kill their prey.
Prey organisms have adaptations that help them avoid being caught and eaten.
Predation can have a major effect on the size of a population.
Symbiosis is a close relationship between two species that benefits at least one of the species.
Mutualism : both species benefit.
Commensalism : one species benefits ; the other is neither helped nor harmed.Demodex mites
Parasitism: Parasite (lives on or in) benefits; host is harmed.Tapeworm head
