- resource partitioning
- secondary succession
- a The division of environmental resources by coexisting species such that the niche of each species differs by one or more significant factors from the niches of all coexisting species
- b A symbiotic relationship in which the symbiont (parasite) benefits at the expense of the host by living either within the host (as an endoparasite) or outside the host (as an ectoparasite)
- c All the organisms that inhabit a particular area; an assemblage of populations of different species living close enough together for potential interaction
- d A force that changes a biological community and usually removes organisms from it. Disturbances, such as fire and storms, play pivotal roles in structuring many biological communities
- e A type of succession that occurs where an existing community has been cleared by some disturbance that leaves the soil intact
5 Multiple Choice Questions
- The mutual influence on the evolution of two different species interacting with each other and reciprocally influencing each other's adaptations
- The concept that when populations of two similar species compete for the same limited resources, one population will use the resources more efficiently and have a reproductive advantage that will eventually lead to the elimination of the other population
- An interaction between species in which one species, the predator, eats the other, the prey
- The "job" a species plays in a community, e.g. small seed consumer, top predator.
- Species that are not usually abundant in a community yet exert strong control on community structure by the nature of their ecological roles or niches
5 True/False Questions
pathogens → a disease causing organism
mutualism → A symbiotic relationship in which the symbiont benefits but the host is neither helped nor harmed
evenness → The simple count of number of species in an area.
richness → The simple count of number of species in an area.
primary succession → A type of ecological succession that occurs in a virtually lifeless area, where there were originally no organisms and where soil has not yet formed
