THE DECIDUOUS FOREST
Transcript of THE DECIDUOUS FOREST
the Deciduous Forest Biome Deciduous Forest World Map * The yellow is the deciduous forest The Deciduous Forest's Climate The deciduous forest has a latitude of 23 degrees north to 38 degrees south.The summers are mild, averaging around 70 degrees Fahrenheit. The winter starts around December, with average temperatures of about a little below freezing. The annual rainfall year round is 750 mm to 1500 mm. It increases every month from 15 mm to about 65 mm January through August and the decreases back down to 15 mm from September to December. Landscape This area is covered in trees. It can be located on hills and mountains in some areas and on flat land in others. The leaves fall off during the fall and when they do, the nutrients from the leaves get added to the soil. Because this happens, the land there is very fertile and it has a long growing season. Representative Plants Hickory: A large tree that can grow up to 120 feet tall. It is made up of hard wood. Also it has compound leaves. Its roots go deep into the ground so it is very stable and can take a lot of wind.The plant produces nuts that are round and green and are eaten by both man and animals. Hemlock: Can grow up to 40 to 60 feet in height. It can live up to 800 years. Its made up of soft bark that is brownish grey. The wood from it is used to make paper. Has needle- like leaves that are small, flat, green, and pointed. Representative Animals American Black Bear: A type of bear that mostly only lives in North America. It can run up to 25 miles per hour and it weighs from 220-594 ponds. They have rounded ears, a short stubby tail, and short claws to use for climbing trees. They are usually black but can have a little bit of brown, cinnamon, and other colors in it. The length of the bear is 5 to 6 feet from nose to tail and is 32-38 inches from its shoulder to its paw. Valuable Natural Resources A valuable natural resource of of the deciduous forest are trees.This natural resource is important to us because it is used to make paper. Also it is important because trees produce oxygen which we use to breath. They are used for many other things such as construction. They also provide a home to many animals. Lastly trees are important because they bring a beauty to the natural world the both humans and animals enjoy. A way we can conserve this natural resource is by recycling paper so that less trees will have to be cut down. Also they can be conserved by not cutting down trees unnecessarily and only do so if needed. Endangered Species A natural resource is a resource from nature that humans use or use a form of in their everyday lives. An endangered species is a type of species that there is such a small number of left that it is on the verge of extinction. An example of an endangered species is the long-eared owl. One reason why it is endangered is because of the deforestation of its homes to turn into farm land, housing, and other reasons. Also it's because its main food source, vole and mice, don't have anywhere to live so they aren't able to hunt it. Ways these owls had been helped are in some places where natural nesting habitats have been decreased, artificial baskets are placed for them to nest in. Also land management people have been saving grasslands and nesting grounds along with planting trees to help these animals out. White-tailed Deer:A type of deer that lives in Southern Canada, mainland United States, and Central America through Bolivia. The males of this species can weigh up to 400 ponds while the women can weigh yup to 200 pounds and their shoulders can be from 3 to 3.5 feet long. Only males have antlers which the lose from January to March and grow back again in April or May. They eat green plants in the summer and and nuts, acorns, and other types of plants in the winter. Their fur is grayish in the winter and reddish in the summer and it covers most of their body. It has a protective coloring that provide the animal camouflage. These animals are usually solitary but in the winter they form herds to stay warm. They were endangered animals at one point in the Midwest of the United States but once hunting restrictions were placed, its population grew back again. Global Warming Global warming is when the earth gradually gets warmer due to greenhouse gases. Specific Characteristics to Fish One characteristic specific to fish is they have gills instead of lungs. They have fins to swim which is something no other vertebrate group has. Fish have a lateral line system along the side of them to sense vibrations in the water. Global warming is affecting the deciduous forest by increasing its temperature and also by decreasing its rainfall amounts. This causing the plants to not get enough of rain to grow. Also it is warming up so that some of the plants and animals aren't able to live there anymore. If global warming continues, then all the plants and animals will either have to adapt to the climate. If they don't they will die, or in the animals case have to move away. Fish are born with ability to swim, meaning as soon as they come into life they can swim which is something other vertebrate groups can't do. Fish are a vertebrate group with a backbone that live in the water. The golden-scaled fish eats algae, mosquitoes, and microorganisms which it finds in the rivers where it lives and just algae and microorganisms when it goes off to the ocean. It finds its food in the rivers where it lives. It eats 3 times a day in the morning, afternoon, and night. When it has its food, it eats in small quantities. Eating Habits Carrying Capacity A limiting factor of the golden-scaled fish are black bears. They eat my animal and reduce its numbers. Another limiting of my animal is the American Bald Eagle. In its biome this animal eats my animal and keeps its population under control. A third example of a limiting factor is a lack of food. There are so many fish in the rivers where it lives who eat same things it eats does that there is competition for food and its numbers reduce. The carrying capacity for my animal in its biome is 1500 of it. 2009 2010 2011 2012 1200 1600 1000 800 1400 600 Key - my animal 10 20 30 40 50 60 - American Bald Eagle Number of the Golden-Scaled Fish Number of American Bald Eagle Year Food Web Grass Producer Algae Producer My animal
Omnivore Eastern cottontail rabbit Primary Consumer Herbivore American Bald Eagle Secondary Consumer and Decomposer Carnivore American Black Bear Secondary Consumer Omnivore Fungus Decomposer Habitat Habitat: The natural environment of an organism. The specific habitat of the golden-scaled fish in the deciduous forest is the middle area of the river. This is it's main home but for a short time once its a little older it goes off to live in upper middle part of the ocean that the river it lives in dumps into. This is possible because it is an animal that can survive in both freshwater and saltwater. That is where my animal sleeps, lives, sleeps, and does everything else. Adaption to Climate In the winter the golden scaled fish go deeper into the water away from the cold. Also it has a special protein in its body that keeps it from getting too cold. How it attracts a Mate An adaption of my animal to attract a mate is the male change colors and makes themselves more attractive looking for the women and then they swim along the women and try to "mingle" with them by using their body movements and making sounds. Mutualistic Relationship between The Golden-Scaled Fish and Salmon The Golden-Scaled Fish has an adaption that allows it to it eat harmful algae that a lot of fish can't have. This fish eats the toxic algae in the rivers to get nutrients from it while it helps other fish such as salmon stay safe and not die. Mutualism: A type of symbiosis where both animals involved are benefited by it. Commensalistic Relationship between Golden-Scaled Fish and Green Seaweed Climate: The type of weather in a general area over a long period of time. Commensalism: A type of association between two organisms where one benefits and the other doesn't get affected. The golden-scaled fish has a commensalistic relationship with green seaweed. The golden-scaled fish lives in the river and the ocean and the green seaweed can live at the place where the river dumps into the ocean along with the ocean so when the golden-scaled fish is traveling to the ocean and back it uses the seaweed as a place to hide from bigger fish that could possibly eat it. By doing so the golden-scaled fish is getting protection from possible predators and the seaweed isn't harmed in any way. Parasitic Relationship between Golden-Scaled Fish and Hydra Parasitism: A type of relationship where one organism benefits and the other is harmed. The golden-scaled fish and hydra have a parasitic relationship. Hydra wrap itself around the golden-scaled fish and many other organisms and feed off of it, harming the organism (which includes the golden-scaled fish) and eventually killing it. Conclusion The deciduous forest is an interesting biome. It has different types of climate throughout the year and is home to many different types of plants, animals, and other types of organisms.The golden-scaled fish which lives in this biome is also a special type of fish. It can live in both the river and the ocean. It is also a small fish, only eating plants and small insects. Because of its smallness it is able to hide from big animals that might eat it but it is also subject of food in its biome. The average lifespan of this animal is 2-3 years. Ihe golden-scaled fishs' overall success in its biome is high; placed as least concern on the endangered species list. As you can see this is an intriguing animal that even though it is small, its still an important animal in its biome. By Sai Nune
