There are many Ecosystems in a Biome  


Freshwater Biome

Marine biome

Temperate Deciduous Forest

Pennsylvania is mostly a temperate deciduous forest. It consists mainly of trees that lose their leaves in the winter and grow them back in the spring.

Coniferous Forest

These forests are ones that stay green all year round and they are made up of trees with pine needles.




Trophic Levels


Gathers its energy from the sun and gets 100% of energy.  

Primary Consumer

  gets 10% of energy

Secondary Consumer

gets 1% of energy transfer

Tertiary Consumer

Gets .1% of energy.


Food Web

Has a lot of food chains in one.

Food Chain



It is a living thing,a piece of a living thing, or at once was living.


Never was living or never will live.

Smallest to largest


a living thing


a variety of species living together in an ecosystem.

Species Biodiversity

Many different species together.

Ecosystem Biodiversity

Difference and types of organisms

Genetic Biodiversity

Same species but different

Hot Spots

Hot Spots are where the greatest concentration of species is located.


Endangered Species

A species in danger of extinction throughout most or all the area it inhabits.

Threatened Species

a species likely to become endangered in the near future.

Indicator Species

Are plants and animals that, by their presence, abundance, lack of abundance, or chemical composition, demonstrate some distinctive aspect of the character or quality of an environment.

Pioneer Species

a Species that creates the base for other organisms.


Ecological Succesion

is a process in which the communities of an ecosystem change over time.

Primary Succession

Life takes over where an ecosystem has never existed before.

Secondary Succession

The process that begins in an ecosystem when something has disturbed or destroyed the natural community.

Population Growth Rate

How fast it grows           (The speed at which it grows)

Exponential Growth

Booming Population.


Booming Population, A j- curve is the same as exponential growth.


When a population reaches carrying capacity.

Population Growth

The births minus the deaths that equal how much the entire population has grown.

How to keep the human population in check.

Limiting Factors

Conditions of the environment that limit the growth of a species. Biotic and abiotic factors that prevent the continuous growth of a population.

Carrying Capacity

The number of individuals of a species that an ecosystem can support.

Climax Community

is one that forms in the last stage of succession.


Water Pollution

The addition of harmful chemicals to natural water. Sources of water pollution in the United States include industrial waste, run-off from fields treated with chemical fertilizers, and run-off from areas that have been mined.

Inorganic Pollutant

Organic Pollutant

Point Source

Sewer and other pipes that empty directly into rivers and streams at one spot and the source of the waste can be identified.

Non-Point Source

Pollution is not coming from a specific source, but from many sources which are difficult to pinpoint.


Natural Resources

resource from the earth

Renewable Resources

A natural resource is a renewable resource if it is replaced by natural processes at a rate comparable or faster than its rate of consumption by humans.

Non-Renewable Resources

A non-renewable resource is a natural resource that cannot be produced, re-grown, regenerated, or reused on a scale which can sustain its consumption rate.



A low-lying area of land that is saturated with moisture, especially when regarded as the natural habitat of wildlife. Marshes, swamps, and bogs.


something that drains or flows off, as rain that flows off from the land in streams.


the process by which the surface of the earth is worn away by the action of water, glaciers, winds, waves.


a region drained by, or one that contributes water to a stream, lake, or other body of water (Drainage Basin).


geological formation containing or conducting ground water, one that supplies the water for wells, springs.

Water Purification

the process of removing undesirable chemicals, materials, and biological contaminants from raw water.


The removal of salt or other chemicals from something, such as seawater or soil.


A surface where water can't be absorbed into the ground.


the process by which large numbers of people become permanently concentrated in relatively small areas, forming cities.
