Environmental Review Vocab Day 1

Exponential Growth

• J-curve (population growth that has not reached a limit)

• Linear Growth (steady increase over time)

• Logistic Growth (population growth that levels off)

• Negative Growth (decrease in population over time)

Population

• The total number of individuals in a species

• The members of a species that live in the same area

• The variety of species in a given area

• The number of individuals in a specific habitat

Immigration

• The movement of individuals OUT of an area

• The movement of individuals INTO an area

• The process of obtaining citizenship

• The act of traveling to a different country for tourism

Logistical Growth

• S-Curve (population growth that slows as a result of limiting factors)

• Exponential Growth (unrestricted population growth)

• Linear Growth (constant increase over time)

• Random Growth (population growth with no pattern)

Emigration

• The movement of individuals EXITING an area

• The movement of individuals ENTERING an area

• The movement of individuals STAYING in an area

• The movement of individuals RETURNING to an area

Population Size

• The total area inhabited by a species

• The number of individual organisms present in a population at a given time

• The average lifespan of organisms in a population

• The genetic diversity within a population

Population Density

• The total number of organisms in a habitat

• The number of individual organisms per unit of area

• The average size of organisms in a population

• The variety of species in a given area

Limiting Factors

• A factor that restricts the growth of a population

• A factor that enhances the growth of a population

• A factor that has no effect on population growth

• A factor that only affects the environment

Carrying Capacity

• The maximum number of individuals an environment can support

• The total number of species in an ecosystem

• The average lifespan of a species in a habitat

• The minimum resources required for survival

Environmental Quality

• The measure of the health of an ecosystem.

• The amount of pollution in the air.

• The diversity of species in a habitat.

• The temperature of the environment.
