This science studies very small life forms, like bacteria, parasites, fungi and algae.
What is microbiology?
100
This is a representation of the simplest path that energy takes in an ecosystem, showing the organisms on each trophic level.
What is a food chain?
100
This covers approximately 71% of the Earth's surface, but only about 3% of it is fresh.
What is water?
100
This law states that matter cannot be created nor destroyed.
What is the Law of Conservation of Matter?
200
Found on the Periodic Table, these are pure substances that cannot be changed into simpler substances.
What are elements?
200
This hard outer shell on a virus protects the genetic material inside.
What is the capsid?
200
These preserved parts of ancient animals and plants play a large part in our understanding of evolution.
What are fossils?
200
These vents are found on the ocean's floor, and release mineral-enriched, heated water that has seeped into cracks in the sea floor.
What are hydrothermal vents?
200
This law states that, in an undisturbed location, the rock on the bottom is the oldest, and the rock on the top is the newest.
What is the Law of Superposition?
300
This man organized the elements and created Periodic Table.
Who is Dmitri Mendeleev?
300
These prokaryotic (unicellular) organisms reproduce by splitting in two, a process called binary fission.
What are bacteria?
300
This occurs in organisms' genetic code, causing them to be different from others in their species. If it is favorable, this will be passed down to the next generation.
What is a genetic mutation?
300
The continuous movement of water around the Earth is known as this.
What is the water cycle?
300
This scientific theory explains how species have changed over time due to genetic mutation and survival of the fittest.
What is the Theory of Evolution?
400
This type of mixture contains several easily distinguishable substances. (Examples: a salad, granite, iced tea)
What is a heterogenous mixture?
400
Instead of seeds, fungi use these to spread and reproduce.
What are spores?
400
This type of consumer eats only other consumers.
What is a carnivore?
400
An area where fresh- and saltwater mix, causing variations in salinity and biological activity, is called this.
What is an estuary?
400
This man is credited as the first person to propose the Theory of Evolution.
Who is Charles Darwin?
500
In a chemical equation, these numbers written to the lower right of elements indicate how many of each type of atom are present.
What are subscripts?
500
This term refers to a global spread of disease to very many people.
What is a pandemic?
500
This is the ultimate source of energy in all food webs.
What is the Sun?
500
This term describes the process by which warm water is blown away from the ocean's surface, causing cold water from the bottom to rise, bringing sediment and organic material to the surface.
What is upwelling?
500
This theory explains how continental and oceanic plates shift around the world, creating land forms like mountains, volcanoes, and canyons, as well as causing earthquakes.
