1.1 Species Interactions (BIO)
Mutualism
a symbiotic relationship in which both species benefit
Commensalism
an interaction that benefits one species and does not affect the other species at all
Competition
an interaction that harms both species
Parasitism
an interaction that harms one species and benefits the other species
Exemplified by moss growing on a tree trunk in a forest.
commensalism
Exemplified by starlings displacing bluebirds from nesting sites
competition
intraspecific
competition between the same species
interspecific
competition between two different species
Exemplified by bees consuming nectar and carrying pollen from one flower to another
mutualism
Exemplified by ticks feeding on a deer
parasitism
Resource partitioning
when similar species settle into separate niches that let them coexist - using the resources in different ways, places, or at different times can reduce the negative impact of competition on survival
Predation
where a predator eats its prey
