Transcript of Ecosystems:Biotic& Abiotic Factors

Sun Avalibabilty TUNDRA Animals... Tundra Plants Savanna Abiotic Factors Water Savanna Aboitic Factors Abiotic Biotic Precipitation Snowfall Tundra Animals Greenhouse Gases Creates lakes, and rivers which is an important
source of fresh and living resource. Also is vital for the process of snowfall. Rain! Helps the vegetation grow which allows more nutrients for animals.

It increases the food supply and drinking water supply.
Creates watering holes for animals! Tundra Plants Helps animals to camouflage when in danger, and the snow becomes a good insulator by slowing down the exchange of heat. T Tundra Tundra Plants Savanna Plants How does Biotic and Abiotic factors shape ecosystems? Some of the primary producers that are in the savanna are the Carbon dioxide, water vapor, and other natural gases that is released increases the earth's temperature. When the earth's temperature continuously increases it contributes to global warming! Soil The tundra has a special types of soil called permafrost which does not allow many plants and trees to grow there. This affect the food web because it reduces the amount of producers available to the biome. Biotic Factors Plants Some of the plants and vegetation that the permafrost allows to grow is moss, grass, lichens, sedges, and shrubs. The tundra also have a small amount of flower species. Only about 400 kind of flowers! Animals Many of the animals are mammals that have fur, or aquatic animals that can with stand cold temperatures. The pictures above show a polar bear, caribou, snowy owls, salmon and cod. These animals learned how to adapt to the harsh winter in order to survive. This changes the animals life style and behaviors. Food Availability/Chain In the tundra ecological pyramid primary producer are the small amount of plants that thrive in the tundra. the primary consumers are herbivores. These animals are caribous, lemming, and others animal that eat lichens and moss. The secondary consumers are carnivores. These animals are grizzly bears and other types of bears that eat fishes and other autotrophs. The tertiary consumers are carnivores. Some of the omnivore animals are the arctic wolves, and polar bears, which both eat the secondary and primary consumers. http://www.buzzle.com/articles/tundra-food-chain.html This is the website that has the information about he specific kind of animals for the different types of consumers. Temperatures The temperatures in the tundra can be anywhere from below freezing, to 12 degrees Celsius. The temperature can become drastically low to the point of -28 degrees Celsius. When the temperature is this low, some animals are forced to migrate to warmer areas. Other animal have to adapt to the harsh weather by being able to endure the small extremities of body heat loss. Animals Prey Predators Symbiotic relationships Types of Animals Herbivores Omnivores Carnivores Omnivores are animals that only eat plants Carnivores are animals that only eat meat Herbivores are animals that eat both meat and plants/vegetation. Detritivores Detritivores are animals that only eat detritus. Scavengers Scavengers are animals that only eat carcasses of dead animals. Cow Caterpillar Giant River Otter Snakes Bears Pigs King Vulture Snail Shrimp Aboitic Factors Biotic Factors Competition Animals compete for food. This affects the population f the organisms. Animals compete for mates. This has an affect on animals because it forces them to maintain a certain position in their herd/pack or flock. Animals compete for resources and territory Interspecific Intraspecific Mutualism : A symbiotic relationships that benefits both organisms. This affects the ecosystems because it affects how animals interact with one another This affects the population for animals. This affects the community in a certain area. A hermit crab with a sea anemone on its back Commensalism : A symbiotic relationship that benefits one organism and the other organism remains neutral/unaffected. This is a picture of a remora on the
back of a shark Parasitism : A symbiotic relationship in which one organism benefits while the other organism is harmed. This is a mistletoe invading its roots into the tree. Predators affect the food web because when predators increase prey decrease, and when predators decrease prey increase When prey increase predators increase, and when prey decrease predators decrease because that is their food resource. Erosion Wind erosion shapes the lands and rocks Water erosion shapes rocks, canyons, mountains, and it help turn rock into soil. Natural Disasters Wildfires spreads quickly and it can destroy everything that it spreads to. It devastatingly affects forest and it can even destroy the soil. UV radiation that is released into the atmosphere as radioactive chemicals affects all biotic factors. Temperatures Low Temp. Low temperatures in certain areas causes the clouds to snow, increase wind speed, and animals that live in extremely hot areas (like the dessert) it allows them to be outside during the middle of he day from under the shade. High Temp. High temperatures in some area causes the seasons to change, and in really cold areas (like tundra and the arctic), when the temperature is continuously warm the ice and snow begin to slowly melt. How does aboitic factors and biotic factors affect the savanna? How does aboitic and biotic factors affect the tundra? Virginia wild rye
-cool season grass Side oat grass
-warm season grass There are also many isolated trees in the Savanna. This is a Candelabra tree, and it is very poisonous! Animals Many of the animals in the Savanna are mammals that can tolerate hot/warm weather and dry land. Keystone Species Rain! Helps the plants grow and gives nutrients to plants. It also make watering holes for the animals! The keystone species in the Savanna is the African elephant because African Elephants eat trees and destroy the tree trunk. This is an essential part to the Savanna biome because if the tree population was not maintained in small amounts then the tree would take over the grassy plain, and the savanna would turn into a forest or woodland. A lot of sunlight. Sunlight! increase the growth of grass in open
areas but not in areas where trees cover the grass as much In places, areas where
there is a lot of sunlight
many animals will become
less active during the middle
of the day.
A lot of sunlight increases
the temperature and it helps
with the process of photosynthesis
for primary producers. Soil! The savanna has compact soil! Small amounts of sunlight. The ocean and the auquatic are greatly affected by the amount of sunlight. In some aread, only certain types of plantand animals live in an area where there is not a lot of sunlight. Simian Immunodeficiency is a common diease int h savanna. If it spreads rapidly in the community of animals it could affect the population. Disease Location The location of some areas restrict the amount of sunlight. Artic, Tundra, lowest sea level. The location where the majority of vegitation grows changes where most animals habitats are and their biomes.
