Population – group of individuals of the same speciesliving in the same area, potentially interacting
Community – group of populations of different speciesliving in the same area, potentially interacting
What are some ecological interactions?
Why are ecological interactions important?
Interactions can affect distribution and abundance.
Interactions can influence evolution.
Think about how the following interactions can affectdistribution, abundance, and evolution.
Types of ecological interactions
competition
predation
parasitism
mutualism
commensalism
symbiosis
Competition – two species share a requirement for alimited resource reduces fitness of one or both species
Predation – one species feeds on another enhancesfitness of predator but reduces fitness of prey
herbivory is a form ofpredation
Parasitism – one species feeds on another enhancesfitness of parasite but reduces fitness of host
Mutualism – two species provide resources or servicesto each other enhances fitness of both species
Commensalism – one species receives a benefit fromanother species enhances fitness of one species; noeffect on fitness of the other species
Symbiosis – two species live together can includeparasitism, mutualism, and commensalism
