question
Point Source Pollution
answer
This is any single identifiable source of pollution from which pollutants are discharged.
question
Pollution
answer
This is the contamination of an environment beyond natural correction.
question
Population
answer
All the individuals of a species that live together in one place at the same time.
question
Population Cycle
answer
This is the fluctuation between periods of high and low densities in the number of individuals in a population.
question
Population Density
answer
The number of individuals of a species per unit area.
question
Population Dynamics
answer
This is the way in which a species' population grow and shrink over time.
question
Population Size
answer
The number of individual organisms of a particular species in a group.
question
Predation
answer
This is the condition in which one living organism serves as a food source for another.
question
Primary Productivity
answer
This is the rate at which primary producers produce biomass.
question
Primary Succession
answer
This is the specific type of succession which occurs when the environment becomes void of any life or soil.
question
Producer
answer
This is an organism that supplies matter and energy, also known as an autotroph.
question
Punnett Square
answer
This is a diagram that shows the gene combinations that might result from a genetic cross.
question
Rain Forest
answer
This is one of the seven major biomes in which rainfall amounts are high and flora and fauna vary greatly; at least one-half of the the world's species are contained in these and primary productivity is extremely high.
question
Recessive Allele
answer
This is a form of a gene that is hidden by another, dominant, form of the same gene.
question
Recycle
answer
This is the process of breaking down resources and reusing them in some fashion.
question
Recycling
answer
This is the act of reusing items again.
question
Renewable
answer
This is a type of resource that is replenished by a natural resource faster than it is consumed.
question
Replication
answer
This is the copying process by which a cell duplicates its DNA.
question
Reproduction
answer
This is the biological process of creating a new organism.
question
Reproductive Isolation
answer
This is some barrier to reproduction among a species of organisms. It often results in genetic change over time and the development of new species.
question
Resource Partitioning
answer
This is when organisms coexist by sharing different resources within their habitat.
question
Secondary Succession
answer
This is the specific type of succession which occurs after a event which simply reduces the already established ecosystem (as opposed to destroying it completely).
question
Sexual Reproduction
answer
Process by which two cells from different parents unite to produce the first cell of a new organism.
question
Shelter
answer
This is one of the basic needs for survival. It is a component of an organism's living space and it provides protection from the environmental elements, a place to breed, and sleep or hibernate.
question
Solar Energy
answer
This is the utilization of radiation from the sun.
question
Speciation
answer
This is the origin of a new species in evolution, there are many different methods by which this can occur. Different species cannot reproduce successfully.
question
Species
answer
These are groups of reproducing populations that are isolated from other groups.
question
Succession
answer
This is the regular progression of species replacement that occurs after a disturbance, such as natural disaster, or during the establishment of a new habitat.
question
Survival
answer
This is the set of skills and abilities necessary for an organism to live.
question
Survival Of The Fittest
answer
This phrase, found in Darwin's Origin of Species, suggests that species adapt and change by natural selection and the changes aid in the survival of the organism.
question
Sustainability
answer
Meeting the needs of the present without compromising the ability of future generations to meet their own needs.
question
Technology
answer
This is the use of scientific tools to help make things easier and better.
question
Ten Percent Rule
answer
This is a rule that states only ten percent of energy available at one trophic level is actually passed up to the next.
question
Terrestrial
answer
This is a type of biome which is found on the land.
question
Thermal Pollution
answer
This is a type of pollution associated with increases of water temperatures in a stream, lake, or ocean due to the discharge of heated water from industrial processes, such as the generation of electricity.
question
Threatened Species
answer
An organism facing extinction through destruction of habitat; the process may threaten the survival, abundance or evolutionary development of the species.
question
Trait
answer
A specific characteristic that varies from one individual to another.
question
Trophic Level
answer
This is the position that an organism occupies in a food chain - what it eats, and what eats it.
question
Volcano
answer
This is a landform that is formed by the eruption of magma through a vent from the interior of the earth.
question
Water Cycle
answer
This is the circulation of water between land, air and surface.
