There are many Ecosystems in a Biome
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.
These forests are ones that stay green all year round and they are made up of trees with pine needles.

Population, Community, Ecosystem, Biomes
a variety of species living together in an ecosystem.
Many different species together.
Difference and types of organisms
Same species but different
Hot Spots are where the greatest concentration of species is located.
A species in danger of extinction throughout most or all the area it inhabits.
a species likely to become endangered in the near future.
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.
a Species that creates the base for other organisms.
is a process in which the communities of an ecosystem change over time.
Life takes over where an ecosystem has never existed before.
The process that begins in an ecosystem when something has disturbed or destroyed the natural community.
How fast it grows (The speed at which it grows)
Booming Population, A j- curve is the same as exponential growth.
When a population reaches carrying capacity.
The births minus the deaths that equal how much the entire population has grown.
Conditions of the environment that limit the growth of a species. Biotic and abiotic factors that prevent the continuous growth of a population.
The number of individuals of a species that an ecosystem can support.
is one that forms in the last stage of succession.
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.
Sewer and other pipes that empty directly into rivers and streams at one spot and the source of the waste can be identified.
Pollution is not coming from a specific source, but from many sources which are difficult to pinpoint.
resource from the earth
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.
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.
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.
