- a The simple count of number of species in an area.
- b A type of succession that occurs where an existing community has been cleared by some disturbance that leaves the soil intact
- c 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)
- d An ecological relationship between organisms of two different species that live together in direct contact
- e The "job" a species plays in a community, e.g. small seed consumer, top predator.
5 Multiple choice questions
- 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
- A symbiotic relationship in which the symbiont benefits but the host is neither helped nor harmed
- Transition in the species composition of a biological community, often following ecological disturbance of the community; the establishment of a biological community in an area virtually barren of life
- A defense where one species is selected to look like another species which has an effective defense.
- All the organisms that inhabit a particular area; an assemblage of populations of different species living close enough together for potential interaction
5 True/False questions
mutualism → A symbiotic relationship in which the symbiont benefits but the host is neither helped nor harmed
primary succession → A type of succession that occurs where an existing community has been cleared by some disturbance that leaves the soil intact
competitive exclusion → 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
pathogens → The simple count of number of species in an area.
coevolution → An interaction between species in which one species, the predator, eats the other, the prey
