Temperate Deciduous Forest: 
Representative ​Ecosystem Description​

       A Temperate Deciduous Forest is a biome found in eastern United States and Canada, most of Europe, and areas of China and Japan. This biome has four distinct seasons: fall, winter, spring, and summer. Here, winters are cold and summers are hot. Precipitation happens year-round, its levels per year between 30 and 60 inches. Changes within the Temperate Deciduous Forest biome include changing colors of the leaves in fall and winter versus spring and summer, as well as falling of leaves in the fall and winter. Temperate Deciduous Forests contain some of the largest populations due to its fertile soil and biotic factors (ex: hardwood trees) that allow for a thriving civilization.
       Biotic factors within the Temperate Deciduous Forest include, but are not limited to, plant life such as lichen, moss, and fur on the forest floor, shrubs, and conifers and hardwood trees such as maple oak, and birch. Animal life is very diverse in this biome. In order to live here, animals must be able to adapt to change, some migrating or hibernating in the winter. Most common are insects, spiders, slugs, frogs, turtles, and salamanders. This biome is home to birds such as hawks, cardinals, and owls, and mammals like deer, raccoons, porcupines, and foxes. 

       Abiotic factors are nonliving features of the environment such as sunlight, temperature, and water. In regards to sunlight, winter days are short with little sunlight, and summer days are long and sunny. The average annual temperature in this biome is 50 degrees Fahrenheit, although a range of temperature is found throughout the year as the seasons change. In the Temperate Deciduous Forest, one important abiotic factor is soil. The soil found in this biome is rich in nutrients as a result of decaying material that has broken down into rich organic material called humus. This humus-rich soil is also great at holding water, making it available for plant use, and then able to support the food web. This process allows for the Temperate Deciduous Forest to be very biodiverse.

The Temperate Deciduous Forest: Keystone Species

Alyssa Nucci  AP Biology-4 The Temperate Deciduous Forest: Keystone Species        Keystone species are organisms within an ecosystem in which other species largely depend upon, furthermore upholding the sustainability of the ecosystem. In the Temperate Deciduous Forest biome,   a keystone species is the white-tailed deer. This is because their feeding activity can affect many plants and animals in the surrounding environment. White-tailed deer thrive best in forests with biodiversity. In the spring and summer seasons, these deer eat grasses, wildflowers, mushrooms, and woody plant leaves. As fall begins, the deer gravitate towards acorns, fallen fruits, and crops. In winter, deer eat woody vegetation such as twigs, bark, and foliage.         Deer are preyed upon by wolves, coyotes, bears, bobcats, and humans. As prey, their carcasses can sustain other organisms in their environment such as eagles, ravens, crows, etc. D...

The Temperate Deciduous Forest: The Hydrologic Cycle

Alyssa Nucci AP Biology-4 The Hydrologic Cycle        One major biogeochemical cycle of the Temperate Deciduous Forest is the hydrologic cycle. The hydrologic cycle-better known as the water cycle-of this biome begins with the evaporation of bodies of water (in this biome: the ocean and smaller bodies such as lakes, rivers, etc) into the atmosphere, as well as transpiration of plant life (such as trees) into the air. This water vapor then rises to form clouds with condensation. It then cools and condenses into rain or snow within these clouds, falling towards the surface as precipitation. The water flows into these bodies of water through runoff, then either percolates into the soil or evaporates into the atmosphere, beginning the process again.  Akella, Ram. “Temperate Deciduous Forest.”  Prezi.com , 24 Sept. 2012, prezi.com/m/bz46kckapojk/temperate-deciduous-forest/. “The Water Cycle .”  NASA , NASA, pmm.nasa.gov/education/w...

The Temperate Deciduous Forest: Symbiotic Relationships

Alyssa Nucci AP Biology-4 The Temperate Deciduous Forest: Symbiotic Relationships        In a mutualistic relationship, the two organisms benefit from each other. In the Temperate Deciduous Forest biome, an example of mutualism is the relationship between deer and birds. Deer let birds eat the bugs off of their fur. This allows the deer to get rid of these insects, while in turn, the birds gain a sustainable food source.         With commensalism, one organism enjoys the benefits from the other organism without causing any harm to it. An example of commensalism in this biome is the squirrel and the oak tree. The squirrel is able to seek shelter, protection from predators, and food from the tree, while the tree is neither harmed or benefited.         In a parasitic relationship, one organism thrives on another organism, thus harming it. The relationship between deer and ticks is a g...
