The temperate forest biome is known for its deciduous trees and its seasons. It is a mix of deciduous and coniferous trees. This biome experiences all four seasons. In summer, more food is available for the animals and they become livelier. Temperate forests have warm summers, cold winters, and year round precipitation. Temperate forests grow in the Polar Regions in both the Northern and Southern Hemispheres. Most temperate forests are located in the eastern United States, Canada, Europe, China, Japan, and parts of Russia. Deciduous forests are broken up into five zones. The first zone is the tree stratum zone. It is the tallest zone and trees here range from 60 to 100 feet tall. The second zone is the small tree and sapling zone. Newer and shorter trees make up this zone. The shrub zone is the third zone. Shrubs include mountain laurel, huckleberries, and many others. The fourth zone is the herb zone, and contains short herbal plants, like ferns. The Ground zone is the last zone where plants grow on the ground. Each forest receives a different amount of precipitation in the form of rain and snow. Most forests get their precipitation in winter and spring. Annual precipitation in temperate forests ranges from 30-60 in a year. The average annual temperature in a deciduous forest is 50° F. Most temperate forests have a high biodiversity in it. This is because the biome has a very high density of plant life. Some of the plant species commonly found include those of deciduous trees, ferns, birch, beech, and layers of mosses. Similar to other biomes, scientists expect the biodiversity of temperate forests to decrease because of deforestation and by human activity. Producers in a temperate forest food pyramid consist o... ... middle of paper ... ...iving organisms where one benefits and the other is not significantly harmed or helped. One example of this in the temperate forest is the relationship between a squirrel and a tree, because the tree is not harmed and the squirrel gets protection from predators and shelter. Temperate forests are essential to people as they provide resources that are very useful in our daily lives. Acid rain is main problem to this biome which is caused by us humans. Because of our pollution from our vehicles which harms the leaves of trees, acid rain causes them to yield fewer seeds. However, there are many things that you can do to help sustain life in the temperate forest biome. First of all, you can recycle. You will be decreasing the need to cut down more trees. If we want to continue to enjoy these beautiful temperate forests, our biome must be protected with great care.
These are very difficult questions for me personally to answer because I live in the Pacific Northwest, and I have seen the beauty of the old growth forests first-hand.
Depending on the biomes, rainfall and soil can vary. However, the rainfall is typically ranges from 30 cm to 200 cm. In mountainous regions and forest biomes, there would be plenty of rainfall. While in the grasslands, there’s little rainfall. In the temperate zone, there are two main types of trees, coniferous and deciduous. The deciduous trees, in the South, drop their leaves in the winter. Generally, the trees are usually small in height unless in the forest areas. The forests tend to have wide leaves and tall, large trees. The soil in deciduous forests is found to be very fertile. The different amount of rainfall in the forest areas and the grasslands cause the difference between the trees and plant height. The rainfall in forest regions can lead them to be very common with the rainforests. Furthermore, the changes and variation of weather could be the reason as to why the forests shed or don’t shed their leaves. The leaves show a correlation between the fair amount of sunlight during the summer causing the leaves
Due to the moderating effect, this ecozone has long, mild summers (18 to 22°C) and cool, short winters (-3 to -12°C), with around 720 to 1000mm of precipitation, and 180 to 260 growing days annually. The Westerlies can also alter the weather quickly in this ecozone.
Warsaw, Missouri holds the record for both the coldest and the hottest temperatures ever recorded in Missouri ("Missouri Facts and Trivia"). The temperate deciduous forest is home to unique ecosystems and plentiful wildlife and vegetation. The temperature and precipitation in this biome is not too high or too low, hence the word temperate in the name. The terrain in the temperate deciduous biome has a great effect on the adaptations of the living organisms in the area. Missouri belongs in the temperate deciduous forest biome because both regions have similar climate, locations, terrain, flora, and fauna.
The people of the Eastern Woodlands made many tools to help them in their everyday lives. They made spears, weirs, nets, bows and arrows, lances, knives, taps, snares and deadfall for hunting. Most of those tools were made of wood or bark and other forest material. Arrowheads were made from chert, or flint, from sedimentary rocks. They were shaped like isosceles triangles, the smallest arrows were used for hunting birds, the bigger ones were to spear bears or deer. Flint knives were often oval, or teardrop shaped. For fishing they made spears, weirs, and nets. They also made canoes from hollowed-out trees to help with fishing in the lakes and streams. Some other tools they made were axes made of stone to strip bark, clear fields and removing fat from hides. Axes
The vegetation is mostly trees. There are many types of trees, Some of the trees are coniferous trees and deciduous. It is all scattered in the southern part of the Canadian Shield. The forests are all mixed with birch trees, aspen trees, tamarisk trees, black and white spruce trees, willow trees, hemlock trees, pine trees and balsam fir trees. The mixed forests are beautiful in the fall when the leaves of the deciduous trees change color.
Another biome in the park is their temperate forest. Temperate forests have high humidity, high levels of precipitation, and variety of trees are also included. Freshwater biomes surround the park as well.
The Taiga Biome is a large, naturally occurring community of flora and fauna occupying a major part of both Siberia and North America. It is usually found at high elevations at more temperate latitudes in the Northern Hemisphere. It is the largest terrestrial biome on earth, covering around 50 million acres of land (NP, UC Santa Barbara). It is known for its subarctic climate that ranges between -51 to -1 °C in the winter and -21 to 7 °C in the summer. The two main season found in the taiga are summer and winter as autumn and spring are usually very short and barely noticeable. Winter makes up around six months of the year, with only around 50-100 frost-free days during the summer. Summer is also the season during which the taiga receives the most precipitation in form of rain. The remainder is made up of snow and dew, which adds up to around 30-85cm of precipitation yearly (NP, S.L. Woodward).
For a species to survive and flourish within a given environment, it not only needs to replace itself but also all the other species around it exclusively. Hence, if one species completely replaces another species, the result is a single dominant species, a monoculture (source 2). According to Gause’s law, every species in a given environment occupies different niches for survival. Therefore, two separate species competing for similar resources cannot fundamentally coexist (source Gause). This is known as the competitive exclusion principle. When comparing animal niche’s to that of different autotrophic plants, one can rather easily differentiate adequate ecological niches for the animal species merely based on food-requirements (P.J. Grubb). On the contrary, many autotrophic plants contradict the competitive exclusion principle by sharing similar ecological niches such as sunlight, carbon dioxide, water, and alike mineral nutrients (p.j. grubb).
The dense levels of vegetation absorb tremendous amounts of carbon dioxide in the atmosphere and help slow down the rate of climate change that the planet is experiencing. This process also produces high levels of oxygen that help to support life around the world. Coupled with the high levels of rainfall that benefit the water cycle, the rainforests are an integral part of the many systems that exist. These forests contain a wide variety of plants that a source of different chemicals that are used to create medicines. The degradation of these areas could potentially lead to the loss of medicines that could cure some of the deadliest diseases and illnesses that
Temperate grassland biomes can be found in North America, Africa, the pampas of South America and many parts of Eurasia. Grass is the main plant in Temperate Grassland biomes, trees and shrubs are rare to see in this type of biome. Temperate grasslands also have an extremely high abundance of wildlife. The wildlife living in this biome includes bison and pronghorn sheep, but mainly the animals most affected were the cattle and horses that lived on the surrounding farms.
Simply speaking, rainforests are basically the foundation of the earth. The most important role that rainforests play is ‘the lungs of the earth’. This is extremely vital to the earth’s survival as the trees and plants absorb carbon dioxide which they use to help grow and let out oxygen which we need to live. This system is known as the carbon-oxygen cycle and with numbers of rainforests declining, it is highly threatened. The largest rainforest in the world, the Amazon, alone is known to produce half of the world’s oxygen. A break down in the carbon-oxygen cycle means that we will not only have less oxygen, but an increase in carbon dioxide which eventually leads to global warming. This occurs as carbon dioxide traps heat which actually keeps the earth warm, with the right amount of carbon dioxide that is. This is called the greenhouse effect and occurs naturally however due to decreasing number of trees, there is more carbon dioxide than needed which traps extra heat making the earth hotter than needed, this is known as global warming which also causes a rise in sea level.
Ecosystems are the basic biological units of ecology, and consist of biotic organisms and their interactions amongst other living organisms, as well as the surrounding abiotic environment (Putman and Wratten 1984). One facet of ecosystems that is less-often mentioned is the process of decomposition, as it many may view it as an unclean, unpleasant process that occurs after an organism has ceased to exist. To those with an ecological framework, however, decomposition is viewed as the opposite – an interesting, intricate process teeming with biological activity and life (Swan and Kominoski 2012). What is decomposition? Formally, decomposition is defined as the process to which complex organic matter is broken down to its basic constituents (i.e.

Walking through the woods never fails to clear my mind. After spending all day sitting in a stale classroom, filled with stress, confusion, and overwhelming responsibilities, taking a long stroll through the familiar woods behind my grandmother’s house lifts any worries that could ever weigh me down. I never wander through aimlessly. I always follow the trail of grass that has been deliberately cut down shorter than the rest, making it easier to tread through to the small creek at the end of the trail. The entire journey through the woods behind my grandmother’s house, there and back, first took on a whole new importance in my life during my junior year of high school.
