Vocabulary
The first organisms to inhabit an ecosystem.
What are pioneer species?
Rocks, desks, sun, and air are often examples of this.
What are abiotic?
Affects population regardless of size (i.e. weather, natural disasters).
What is density-independent?
Name one difference between primary and secondary succession.
Why is it that primary sucession starts from scratch while secondary there was already an ecosystem, but is was destroyed by a disturbance?
A type of model that is done on the computer.
What is a simulation?
A brand new ecosystem, no one has ever lived there.
What is primary succession?
The sphere of Earth that contains all water.
What is hydrosphere?
Population that grows without a limit (the graph looks like a J shape)
What is exponential growth?
Give two examples of secondary succession.
What are fires and floods?
What is homeostasis?
The relationship where 1 organism is a hunter and the other is hunted.
What is predation?
A relationship between two organisms where one is benefitted and the other is not harmed nor benefitted.
What is commensalism?
Population grows and then levels off when carrying capacity is reached (graph looks like an S shape)
What is logitstical growth?
Name 2 examples of a pioneer species.
What are lichen and moss?
Name the sphere that contains air and name the sphere the contains the solid features of earth (i.e. rocks, dirt)
What is the atmosphere and geosphere?
A model that is a flowchart or diagram.
What is a conceptual model?
A variety of organisms/species found in an ecosystem.
What is the biodiversity?
If a park can only have 10 squirrels, but continues to grow to 15 squirrels. At this point, squirrels are starting to die due to the lack of food. What is this called?
What is carrying capacity?
This is how we know succession is "over," occurs at the very end.
What is climax community?
Explain what would happen to the prey if predators were removed from their ecosystem.
Would the prey eat all their food and die eventually?
Limiting factors that have a larger impact on larger populations.
What are limiting factors?
Order these from smallest to largest: population, biome, organism, community, biosphere, ecosystem.
What is organism, population, community, ecosystem, biome and biosphere?
Describe one living and one nonliving factor that can lower carrying capacity in an ecosystem.
What is disease and water?
If cells cannot take up glucose, then what happens to the persons sugar levels.
Will sugar levels rise?
Occurs when 2 or more organisms are fighting for the same resource (food, water).
What is competition?
