Urbanization

• Process through which cities grow and build up with many people living in a small area

• A method of reducing population density in rural areas

• The decline of urban areas leading to increased rural populations

• A strategy for improving public transportation in cities

Behavioral Adaptation

• an organisms actions or behaviors that enhance the survival and reproductive success in a specific environment

• a physical change in an organism's structure to better suit its environment

• a genetic mutation that occurs over generations to improve survival

• a learned behavior that is not instinctual but developed through experience

Ecosystem resilience

• an ecosystem's ability to withstand and recover from disturbances

• the variety of species within an ecosystem

• the total biomass of an ecosystem

• the rate of energy flow through an ecosystem

Allele

• a type of mutation in DNA

• one of two or more versions of a gene

• a protein that helps in cell division

• a structure that carries genetic information

Natural Selection

• Organisms with traits better suited for their environment are more likely to survive, reproduce and pass on their traits.

• All organisms have an equal chance of survival regardless of their traits.

• Natural selection occurs only in domesticated animals.

• Environmental changes have no impact on the survival of organisms.

Fragmentation

• An area that is being divided or broken into pieces

• A process of combining multiple elements into one

• A method of preserving natural habitats

• A technique for enhancing soil fertility

Selection Pressure

• A force that affects how likely an organism is to survive and reproduce

• A type of environmental change that has no impact on species

• A method of breeding organisms for desired traits

• A measure of genetic diversity within a population

Urban

• Highly populated area

• Rural farmland

• Desert region

• Suburban neighborhood

Survival of the Fittest

• an evolutionary process where organisms best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits

• a theory that suggests all organisms have an equal chance of survival regardless of their traits

• a concept that states only the strongest individuals in a population will survive

• a process where organisms change their traits to adapt to their environment within a single generation

Population

• a group of individuals of the same species living in a specific area and capable of interbreeding

• a collection of different species living together in an ecosystem

• the total number of individuals in a species across the globe

• the number of individuals in a specific area regardless of species
