100
The group in an experiment that does not receive experimental testing
What is the control group?
100
All living things are made of these: either uni- or multi-
What are cells?
100
A group of different species living in a given area
What is a community?
100
Producers (autotrophs) get their energy from here.
What is the sun?
100
The process of one community replacing another over time
What is succession?
200
The group in an experiment that is tested on
What is the experimental group?
200
All the living things in an ecosystem
What are biotic factors?
200
Several different species in an area and the abiotic factors of the environment are all part of this
What is an ecosystem?
200
This shows a single sequence of feeding relationships
What is a food chain?
200
Primary succession occurs after a glacier shrinks or a volcanic island forms because this is not present
What is soil?
300
A testable possible explanation of an observation
What is a hypothesis?
300
The nonliving parts of an ecosytem: water, soil, oxygen.
What are abiotic factors?
300
The largest level of organization
What is the biosphere?
300
This portion of the water cycle occurs when the sun heats up water from trees
What is transpiration?
300
A population that increases at first, then stabilizes and levels off, creating an S-shaped curve, shows this kind of growth
What is logistic growth?
400
In an experiment, this is changed by the scientist
What is the independent variable?
400
The ability to produce offspring
What is reproduction?
400
This biome has evident four seasons, where tree leaves fall in autumn and are replenished in the spring.
What is the temperate deciduous forest?
400
Nitrogen fixation is caused by burning fossil fuels, lightening, and this
What is bacteria?
400
A logistic growth curve stabilizes as it reaches this point
What is carrying capacity?
500
In an experiment, this change is measured by the scientist.
What is the dependent variable?
500
The maintenance of constant internal conditions
What is homeostasis?
500
This biome is the coldest
What is the tundra?
500
Deer who eat grass, are an example of this
What is a primary consumer?
500
After a volcanic eruption, primary succession begins by pioneer species doing this
What is breaking down rock to form soil?
