Transcript of Savanna Biome
Biome Plants Acacia Senegal
Gum tree eucalyptus
Umbrella Thorn Acacia
Whistling thorn Average Climate
Temperature: It is usually cooler during the dry
season. The savanna climate has a temperature
range of 68 degrees Fahrenheit to 86 degrees.
In the winter, it is usually about 68 degrees
to 78 degrees. In the summer, the
temperature ranges from about 78 degrees
to 86 degrees. Precipitation Level: There
is an annual precipitation of 10 to 30 inches
of rain. From December to February, hardly
any rain falls at all. Climate Continued:
Seasonal Patterns: In the savanna climate
there is a distinct dry season, which is in the winter.
Savannas get all their rain in the summer months.
During the distinct dry season of a savanna,
most of the plants shrivel up and die.
Some rivers and streams dry up. Most of the
animals migrate to find food. In the wet season all of the plants are lush and the rivers flow freely. The animals migrate back to graze. In West Africa the rainy season begins in May. Food "Web" Information Producers- star grass, acacia, rod oat grass
Primary Consumer- grasshoppers, mice, impala,hares
Secondary Consumers- mongoose, caracal
Tertiary Consumers- lions, cheetahs, hyenas
Decomposers- termites, nematodes, many species of fungi The Savanna Biome is the largest Biome in southern Africa, occupying 46% of its area, and over one-third the area of South Africa.The Savanna is located around 30 degrees N and 30 degrees S. It is found between tropical rainforest and Desert biomes. It is located in places such as Africa, South America, and Australia. It is well developed over the Kalahari region of South Africa and is also the dominant vegetation in Botswana, Namibia and Zimbabwe. Worldwide location Savannas are subject to regular wildfires and the ecosystem appears to be the result of human use of fire. There are foreign pests and weeds that have been brought to this Biome, such as the wetland weed Mimosa, threatens the survival of the region's ecosystems and native species. When some of the farmers took over land, they brought with them new systems that caused some species to become endangered. The Aboriginal people have been stripped of their homes so that the government can make more room for agriculture. Several Threats to this Biome
A tiny island off the coast of Madagascar is home to the smallest chameleon ever discovered. Scientists believe Brookesia micra, which is just over an inch long, is the result of a double case of "island dwarfism," in which island species shrink as they evolve to adjust to their restricted habitat. Current News Story Example of Predation A Cheetah's prey in this case is
a Gazelle. Example of Mutualism On the African savanna a small bird, kind of like a canry, lives on the back of an elephant, rhino or giraffe. This little bird cleans the creature and rids it of ticks and other pests while in turn the bigger animal, provieds the bird protection from predators. Example of Commensalism Honey badgers follow the honey guide or indicator birds to find bee colonies. The badger opens the hive and feeds. The bird then gets the larvae and wax as food. Human Benefit Invasive Species
Cattle is an invasive species to the Savanna because they are not native to the land, but were imported into the area from a separate region.
The Cattle are over populated in the Savanna, and eat vast amounts of grass.
As they eat the grass they pull out the interior plant. So that the vegetation is not able to grow back
This causes the plants to be unable to reproduce correctly and grow causing them to die. Importance of this Biome
to Planet Earth -African Elephant
-African Wild Dog
-Nile Crocodile Savannas are very important. They are the homes to many animals, some that are endangered and rare. Savannas are where most of the big migrations occur, the biggest on in Africa's grassland, the Serengeti. Here the animals graze, rest, and then migrate for winter, during which time other animals prey on those traveling. Many do not make it to their destination for many different reasons, lack of food and water, or being eaten by another animal. Biodiversity comparison Protection of the Savanna Biome Humans benefit from this biome because it provides a wide array of animal and plant species. This helps because it allows more research to be done which allows humans to have more knowledge. This allows us humans to find things such as medicine and cures, a place for students and scientists to study specific organisms for their research, and a region for tourists to see healthy animals that are not domesticated and tortured by non natural events. Conservation of Savanna is good in principle, mainly due to the presence of the Kruger and Kalahari Gemsbok National Parks within the biome. Similarly, in neighbouring countries, large reserves occur, such as Etosha, Gemsbok, Chobe and Hwange National Parks and the Central Kalahari Game Reserve. All of these national parks help to preserve and conserve the wildlife of the Savanna Biome! To protect this biome more, I would say have NGOs hire wardens throughout the zones to monitor the wildlife by making sure none of the animals are being poached. Biodiversity of the Savanna is very big because the Savanna regions
are around the equator which causes many plant and animal species
to flourish. In other regions, biodiversity isn't as much because of their
climate and latitude. For example, the Tundra biome doesn't flourish
in plant and animal species near as much as the Savanna because
the conditions are very cold and dry, like a freezing desert, therefore
not allowing many species to be there with little biodiversity in the region Parisitism
-Ticks and fleas are two major examples
-The tick is a parisite it will
attach to elephants and suck there
blood. Along with other animals. Savanna Activity
Split up into groups of the organisms in the food chain.
Producers- 10 people
Primary Consumers- 6 people
Secondary Consumers- 2 people
Decomposers- 1 person
Each producer gets 6 pieces of candy(energy). Each producer will throw 5 pieces to the Primary Consumers.
What the Primary Consumers catch, they keep as their energy. What is not caught, is lost energy as in real life.
The Primary Consumers will then throw their all but one piece of their candy to the Secondary Consumers. The same applies for them. Candy dropped equals energy lost.
Whatever candy the Secondary Consumers have left, they will throw at the Decomposer. What he catches is the remaining energy left in the food chain.
If done correctly, this activity should closely simulate the 10% rule as in real life. Organisms
