grass land



conferous forest

temperate desiduous forest

Pennsylvania is maily made out of temperate desiduous forests. That is our biome.

rain forest

food chain

Food chains show you the sequence in which energy is transferred from one organism to the next as one eats the other.


ex: grass

food web

A food web shows what a complete ecosystem looks like. It is a bunch of food chains put together to show how many things one organism really eats.


A comunity is populations of different organisms interacting with one another and the ecosystem.


An ecosystem is a group of different species interacting with one another and the environment as one unit.


Population is a group of the same species found in one spot.


A layer of soil water and air the sustains life. Earth is an example.


An organism is any form of life


Things that were never living. An example would be a plastic desk.  


Things that are or once were living. An example would be grass.


the variety of organisms in a geographic area.

Provides us with:



fibers for clothing

hot spots

17 regions on earth that host more than 50% of the earths animale species. only covers 2% of the earths total area and is mostly located in the tropic areas.

trophic levels

As you go up a level the consumers only get 10% of the original energy so plants start out with 100% of the energy because they make it and everything that eats it afterward only gets 10% of the energy that the thing they eat has. 1.tertiary consumers: .1% 2.secondary consumers: 1% 3.primary consumers: 10% 4.producers: 100%  

Ecological succession

Ecological succession is a series of environmental changes and occurs in different stages. In each stage different animal and plant species can grow. Succesion can happend in water and on land.

Primary succession

Primary succession is when succession occurs in a place that has never sustained life. For example a new island that was created by volcanic activity.

secondary succession

Secondary succesion is succesion that occurs in a place that has already sustained life. an example would be an old abandoned farming field.

limiting factors

Limiting factors are conditions of the environment that limit the growth of a species. some examples are amount of food; amount of land; shelter; sunlight; etc.

carrying capacity

Carrying capacity is the number of individuals of a species that an ecosystem can support. This number depends on the limiting factors.

population growth

The human population growth started increasing in the 1800's because of the industrial rvolution. Every since then the population has been growing faster during a shorter period of time.   For more info go to this website:                                    

black plague

The only event in human history that caused a dip in the population growth.

Industrial revolution

An event in history that jump started the poulation growth in the 1800's.


When a population continues to grow faster i a shorter amount of time it makes a j-curve graph.


When a poulation exceeds its carrying capacity and levels off.

exponental growth

Exponential growth means when a population suddenly increases its numbers.


Sustainability means  an ecosystems ability to stay diversed and prosper.

logistic growth

Logistic growth is when a population reaches its carrying capacity and the population levels off or stpsgrowing. Can be represented as a s-curve.

populatio growth rate

how fast a population grows..


a natural underwater spring(ground water) that makes up 14.3% of earths fresh water/

water pollution

Eather using to much water or polluting or dirting the watre we have left. Leaves us with a unreliable water source.


pollution that comes from one source such as a factory.

non point-source

When the pollution comes from a combination of people doing everyday things.
