Community Ecology
Succession
Random
100
A biological interaction in which a predator feeds on its prey.
What is predation
100
A simultaneous demand by two or more organisms for limited environmental resources, such as nutrients, living space, or light.
What is competition
100
Any species that defines a trait or characteristic of the environment. Can define an ecoregion or indicate an environmental condition such as a disease outbreak, pollution, species competition or climate change. _______ __________ are the most sensitive species in a region, and sometimes act as an early warning to environmental concerns
What is an Indicator species
100
Succession that occurs on surfaces where no soil exits IE: Volcanic Eruptions, Rock exposed by glaciers
What is primary sucession
100
An association between two organisms in which one benefits and the other is harmed.
What is parasitism
200
The dominance of one species over another when both are competing for the same resources.
What is competitive exclusion
200
A close and often long-term interaction between two or more different species. Ex: parasitism, commensalism, mutualism.
What is a symbiotic relationship
200
physical features of an organism that help it survive
What are structural adaptaions
200
a disturbance of some kind that happens to a community that does not remove the soil IE: Wildfires, clearing land
What is secondary succession
200
An association between two organisms in which one benefits and the other derives neither benefit nor harm.
What is commensalism
300
An organism that has special nutritional requirements and lives in a restricted habitat that provides these.
What is a specialist
300
An organism able to utilize many food sources and therefore able to flourish in many habitats.
What is a generalist
300
the things organisms do to survive
What are behavioral adaptations
300
the observed process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.
What is ecological sucession
300
An association between two organisms in which both organisms benefit
What is mutualism
400
The full range of environmental conditions and resources an organism can possibly occupy and use, especially when limiting factors are absent in its habitat.
What is a fundamental niche
400
The part of the fundamental niche that an organism occupies as a result of limiting factors present in its habitat.
What is the realized niche
400
The natural home or environment of an animal, plant, or other organism.
What is a habitiat
400
first species to populate an area
What is a pioneer species
400
An area defined by environmental conditions and natural features, especially climate, landforms, and soil characteristics.
What is an ecoregion
500
Any species that occurs outside of its native range. Also known as exotic species.
What is a non-native species
500
Introduced species that adversely affects the habitats and bioregions they invade.
What is an invasive species
500
The place or function of a given organism within its ecosystem; the organisms place in it’s environment/habitat
What is a niche
500
Succession occurs in response to a ____________, either from the environment or from humans
What is a disturbance
500
A species that has a disproportionately large effect on its environment relative to its abundance, affecting many other organisms in an ecosystem and determining the types and numbers of various other species in the community.
What is a keystone species
