the variable that is manipulated
What is a control variable
a variable you keep the same across groups

What is carrying capacity?
The largest number of individuals of a population that a given environment can support
What is exponential growth?
Growth pattern in which the individuals in a population reproduce at a constant rate with no limiting factors
What is logistic growth?
This occurs when a population's growth slows and then stops, following a period of exponential growth. It often forms a consistent wave that reflects around carrying capacity.
What is a limiting factor?
A factor that controls the growth of a population in an ecosystem
What is ecology?
The study of interactions between organisms and their environment
What is population ecology?
The study of how and why the number of individuals in a population changes over time in a given environment
What is a bioindicator?
An organism that is very sensitive to the environmental conditions and is one of the first respond to changes, used to measure the health of an aquatic ecosystem
What is a food chain?
A series of steps in which organisms transfer energy by eating and being eaten
What is a food web?
a system of interlocking and interdependent food chains representing the organisms in an ecosystem
What is cultural eutrophication?
A type of water pollution whereby chemicals are introduced into a lake or pond creating an excess of nutrients such as nitrates and phosphates.
What is an algal bloom?
The rapid growth of a population of algae in an ecosystem to the point where it becomes overabundant and harmful
What is pH?
A measure of the hydrogen ion concentration of a solution used to determine how acidic or basic a solution is
What is a pathogen?
A microorganism that causes disease
What is the leading cause of death in the world?
Contaminated water
What is point source pollution?
A source of pollution that can be traced to one source
What is non-point source pollution?
Pollution that comes from many sources
How many fecal coliforms can be present in drinking water?
0
What is an introduced species?
Nonnative species that are either intentionally or unintentionally transported to a new habitat but do not cause it significant harm
What is an invasive species?
A non-native species that has spread far beyond its original point of introduction and causes environmental or economic damage by colonizing and dominating suitable habitats
What is mechanical control?
The physical removal of an invasive species
What is chemical control?
The use of pesticides to kill and prevent the spread of invasive species
What is a biological control agent?
the natural enemy of an invasive species that comes from the invasive's native habitat and is used to combat their spread in a foreign ecosystem; includes predators, parasites, and pathogens
What is the main concern of using a biological control agent?
That they become invasive as well
What is the main concern of using chemical control?
Harming other species besides the target species
What is a compound microscope?

A type of light microscope that is used for the observation and manipulation of larger or whole specimens at low magnification
What is magnification?
How much bigger a specimen appears compared to its actual size
What is a prepared slide?
a permanent slide where the specimen is mounted permanently with a mounting medium and a coverslip
