the basic unit of matter
What is an atom?
An explanation that is based on observation, experimentation, and reasoning
What is a theory?
all of the living organisms found in a particular area.
What is a community?
A possible explanation to the question or problem. It is simply a prediction and has not yet been proven or disproven.
What is hypothesis?
main energy source for life on Earth
What is sunlight?
a pure substance consisting of all the same type of atom
What is an element?
means “changes over time.”
What is evolution?
an interaction in which one organism captures and feeds on another organism.
What is predation?
to investigate and understand the natural world, to explain events in the natural world, and to use those explanations to make useful predictions
What is the goal of science? (or what is science?)

What is a food chain?
a giant molecule formed by the joining of smaller molecules
What is a macromolecule?
remains or traces of an organism that died long ago
What is a Fossil Record?
form of deception used by the prey as a means of defense against being eaten.
What is mimicry?
the comparison between a “control group” with an “experimental group.”
What is an experiment?
organisms acquire their energy from other organisms.(that includes humans)
What are Heterotrophs?
sugars, starches, and celluloses
What are carbohydrates?
A method of breeding that allows only those individual organisms with desired characteristics to produce the next generation
What is selective breeding?
the relationship between two different species in which one species benefits from the relationship. The other species is neither harmed nor helped. (ex Shark and Remora)
What is commensalism?
the variable that is deliberately changed by the scientist
What is an independent variable?
organisms that have the ability to use energy from the sun to convert simple inorganic substances into complex organic substances
What are autotrophs?
macromolecules that contain carbon, hydrogen, oxygen and nitrogen
What are proteins?
Those better suited for the environment have a better chance of reproducing.
What is Natural Selection?
the gradual, sequential regrowth of an area following a disturbance
What is succession?
works with one variable at a time. If several variables were changed at the same time, the scientist would not know which variable was responsible for the observed results
What is a controlled experiment?
key element of all organic compounds. All of the carbohydrates, lipids, proteins and nucleic acids that compose all living things contain these atoms
What is carbon?
