community interactions
Competitive exclusion Principle:
No two species can occupy the same niche in the same habitat at the same time. Competing for same resources. Species is eliminated from a community because of competition for the same limited resources.
Resource
refers to anything that is required for life.
Mutualism
+/+ both species benefit from interaction.
Predation, Parasitism, symbiosis
+/- one species benefits, one is disadvantaged
Commensalism
+/0 one species benefits, one unaffected.
Competition
-/- each species affected negatively
Kudzu examples
Competes with native flora for light. Blocks plants access by growing over them and shading them with it leaves.
Community interactions include:
Competition, predation, Symbiosis, Mutualism, Commensalism, Parasitism.
Ecological Community
is to defined as a group of actually or potentially interacting species living in the same area. Whatever affects one species also affects others.
Interference Competition
meaning it out - competes other species for a resource.
Resource might include
food, water, light, nesting sites, or room to grow.
What is Competition
is an interaction between organisms or species, in which the fitness of one is lowered by the presence of another.
Competition occurs
when organisms of the same or different species attempt to use the same ecological resources in the same place at the same time.
