Everything that is alive, was alive, or was produced by the body of a living thing
Biotic Factors
Which type of succession is this: Begins with bare rock, its pioneer species are lichens, and takes longer to reach a climax community
Primary Succession
An ecological pyramid always begins with...
Producers/Plants/Autotrophs
Worms live inside of an organism's stomach and make that organism sick. This is...
Parasitism
How does energy enter and exit an ecosystem?
Enters - Sun
Exits - Heat
A species that is not native to a habitat and threatens the native species
Invasive Species
What is a mature, stable community that undergoes little to no succession (the end result of succession)?
Climax Community
Who eats the producers?
Primary consumers
A bird eats a tick off of a cow. This is...
Mutualism
Which trophic level has the largest biomass and most amount of energy?
Producers/Plants/Autotrophs
An organism that causes dead organisms to decay outside of its body, then absorb the nutrients
Decomposer
Which type of succession is faster? Why?
Secondary, because it already begins with soil
Who eats secondary consumers?
Tertiary consumers
Give me an example of mutualism
Any relationship where both animals benefit
How much energy is transferred to the next level in an ecological pyramid?
10%
An organism that consumes dead organisms (a detritivore)
Scavenger
What are the steps of primary succession?
All of the living and abiotic factors in an area
Ecosystem
A close, permanent relationship between organisms of different species
Symbiosis
Who is most affected by biomagnification?
Apex Predators/Top Consumers
Explain biomagnification
Toxins and pollutants in a food web become concentrated in the top predators
What is succession?
The order of steps in which an environment recovers from damage
Order the levels of ecology from smallest to largest
Organism/Individual, Population, Community, Ecosystem, Biome, Biosphere
Give me an example of commensalism
Any relationship where one species benefits and one is unaffected
The ability to withstand fluctuations in biotic and abiotic environmental factors
Tolerance
