Circulates fresh water between the atmosphere and the earth.
What is water cycle
100
Traces the movement of carbon between living things and the environment.
What is carbon cycle
100
Any special characteristic that helps an organism survive in their environment.
What is adaptation
100
Organisms best suited to the environment will be most likely to survive and produce offspring.
What is the process of natural selection
100
Develop from a common ancestor.
What is homologous structures
200
Rain, snow, sleet, hail.
What is precipitation
200
Represents the movement of nitrogen among the atmosphere, soil, and living systems.
What is nitrogen cycle
200
An idea that attempts to explain how organisms on earth change over time.
What is theory of evolution
200
Breeders, farmers and geneticists control what traits to pass on to future generations.
What is artificial selection

When the last organism of a species dies.
What is extinction
300

Gradual changes of an organism, from one form to another over many generations.
What is evolution
300
The ability of an organism to live, survive and reproduce in a particular environment.

What is competition

When a large percentage of the organisms on earth go extinct. Usually occurs as a result of a catastrophe.
What is mass extinction
500
Water that does not seep into the soil.

What is nitrogen cycle, bacteria
500
A modern form of evidence used to support evolution.
