What is a pioneer species
200
Any species that occurs outside of its native range. Also known as exotic species.
What is Non-native species

Introduced species that adversely affects the habitats and bioregions they invade.
What are Invasive species
200
An association between two organisms in which one benefits and the other is harmed.
What is parasitism
200
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
200
Bees get the nectar they need to make honey by traveling between flowers. The bee brings pollen from one plant to another, resulting in pollination.
What is mutalism
300
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
300
A close and often long-term interaction between two or more different species. Ex: parasitism, commensalism, mutualism.
What is a Symbiotic relationship
300
An association between two organisms in which one benefits and the other derives neither benefit nor harm.
What is commensalism
300
the study of the interactions between species in communities on many spatial and temporal scales, including the distribution, structure, abundance, demography, and interactions between coexisting populations
What is community ecology
300
the things organisms do to survive
What is behavioral adaptations
400
A biological interaction in which a predator feeds on its prey.
What is Predation
400
A simultaneous demand by two or more organisms for limited environmental resources, such as nutrients, living space, or light.
What is Competition
400
Mites will attach to wasps, flies or beetles for transportation.
What is commensalism
400
Organisms that have evolved in a particular region over a long period of time. They have adapted to the climate, hydrology and geology of its region and tend to have a positive impact on the local environment and ecosystem.
What is native or indigenous species
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
500
The dominance of one species over another when both are competing for the same resources.
What is Competitive exclusion
500
An area defined by environmental conditions and natural features, especially climate, landforms, and soil characteristics.
What is an Ecoregion
500
Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows, pigs, and humans. They get food by eating the host's partly digested food, depriving the host of nutrients.
What is parasitism
500
