Biogeochemical Cycles

The Water Cycle

The Water Cycle is important because it supports all of the animals and plants that live there and it gives them life.  The plants need water to carry all important nutrients from the soil to the plant.  The plants need water because they are the base and support of all food chains.

The Nitrogen Cycle

The Nitrogen Cycle is important because plants and animals need nitrogen to produce amino acids, which are then converted to proteins.  These proteins help structure the DNA.  The order of the cycle begins when the plants pass their nitrates to the consumers and throughout the food web.  Once it goes through the food web, it returns to the atmosphere.

The Carbon Cycle

The Carbon Cycle is important because carbon is the basic element for all living things.  Plants consume carbon dioxide.  They consume it to produce their own food and then they produce oxygen and release it.  Animals need oxygen and could not exist without it.  The Carbon Cycle helps animals and plants survive because they need carbon dioxide and oxygen.

Biotic Factors: living things

Deciduous Trees

Abiotic Factors: nonliving things



Climate in a deciduous forest changes from season to season.  On average, summers are around 70º Fahrenheit and winters are around 30º Fahrenheit.  There are about 50-60 inches of rain per year.

History of Population Size

Red-Tailed Hawk

This chart of Red-tailed Hawks from 1966-2003.  The hawk population of births per day has decreased over the years.  


This chart of the Beaver population has shown that they have increased from 1980-2008.



Includes a bald eagle as the predator and a turtle as prey.


The grass and bush growth development is reduced because the tree's shade is blocking them from the sun.


Bees engage in pollination which benefits the bees because it gives them food.  The flowers are able to sexually reproduce for genetic diversity.

The bird is able to get food by eating bugs off the fur of the deer and the deer is being cleaned.


A tapeworm can attach to animals and suck the nutrients from their body's.  

The Oak Treehoppers sucks the nutrients from the oak tree leaves.
