Definitions
The number and variety of species in an ecosystem.
What is biodiversity?
Anything that takes up space and has weight.
What is matter?
Light availability, water availability, nutrient availability, temp, acidity, and salinity.
What are abiotic factors of an ecosystem?
The zone where species can’t tolerate and there will not be any of the species present.
What is the zone of intolerance?
A species dying out and no longer existing on Earth.
What is extinction?
Animals that don’t naturally occur in an area but are introduced due to deliberate or accidental human activities.
What is a non-native species?
The use of chemicals and pesticides to control the population of introduced species.
What is chemical control?
The constant state of conditions within the ecosystem over a period of time.
What is equilibrium?
The evaporation, condensation, precipitation, and collection of water.
What is the water cycle?
Interaction between individuals in the same species or in a separate species.
What are biotic factors in an ecosystem?
The most favourable conditions where species can survive and reproduce.
What is the optimal range?
A species that’s likely to become endangered if factors reducing its survival are not changed.
What happens when a species is threatened?
A non-native species whose intentional/accidental introduction negatively impacts the natural environment.
What is an invasive species?
The use of intentionally introduced organisms to control invasive species.
What is biological control?
When two individuals befitting each other.
What is mutualism?
The travelling of carbon atoms from the atmosphere to Earth and back into the atmosphere through photosynthesis, carbon fixation, cellular respiration, decomposition, and combustion.
What is the carbon cycle?
Any factor that restricts the size of a population. Can be biotic or abiotic.
What is limiting factor?
The zone where organisms are able to survive but not thrive. The weaker organisms will die and the others will have a reduced level of function with an overall low population.
What is the zone of psychological stress?
A species that may become threatened or endangered because of a combination of factors.
What does it mean when a species is under special concern?
When invasive species compete with or feed on native species, leading to population or extinction. Changes the ecosystem dynamics by altering nutrient cycles or energy flow.
What are ecological damages done by invasive species?
The creation of physical barriers such as removal by hand, hunting, and when referring to plants burning or cutting down.
What is mechanical control?
When one individual lives on or in and feeds on a host organism.
What is parasitism?
Shows how matter moves through the biotic and abiotic environment.
What are biogeochemical cycles?
The maximum population size of a species that an ecosystem can sustain.
What is carrying capacity?
A species facing imminent extirpation or extinction.
What does it mean when a species is endangered?
When an invasive species carry diseases throughout different parts of the world.
What are health damages done by invasive species?
When one individual benefits and the other neither benefits nor is harmed.
What is commensalism?
The ability for a species to survive within a range of abiotic factors.
What is the tolerance range?
A species that no longer exists in a certain area.
What does it mean when a species is extirpated?
When an invasive species damages forests and agriculture crops. Native plants have to compete with invasive plants which can hurt crop yields.
What are economical damages done by invasive species?
