Savannah Life

By; Destiny, Chase, Jake, Isaiah, & Jamie

The Savanna Biome is a large expanse and part of Africa. Taking up almost 1/4th of the land.

Energy Pyramids & Life!

This pyramid explains and shows how energy travels from the producers, to the mighty lion at the top. Energy crosses across all streams of life, ranging from Gazelles and grasses at the bottom to Cheetahs and lions near the top.

This fweb shows a little bit ore detail of the tranfer of energey and the relationships between the organisms and the vegetation. Only 10% of the energey, however, is tranfered between them!

The Cycles of the Savanna

The water cycle is a very important part of the Savanna. As you see in the clearly defined picture. Water and perspiration is evaporated from water bodies and organisms and is sent into the atmosphere. It then condenses back into water form and falls back down on to the Earth. The cycle then repeats.

Another cycle is the carbon cycle. The carbon cycle starts when carbon dioxide, made when animals breathing  enters the atmosphere. Carbon dioxide is then consumed by plant life and is turned into carbohydrates through photosynthesis. The plants then put off oxygen. The animals that made the carbon dioxide then eat the plants and the carbon compounds then transfer through the food chain as the animals and plants eventually die. These remains are then consumed by decomposers in the ground. The carbon in their bodies then returns to the atmosphere as carbon dioxide.

The oxygen cycle is the penical of all life on Earth and different areas of the world have different oxygen cycles. The Savanna's cycle is baisc and resembes alot of other regions. Basic plant functions such as photosynthesis are the main driving forces of the oxygen cycle. Plants  

One biotic factor of the african savanna are the shrubs and grasses. In the savanna grasses are the dominant plant life. Some grasses can grow between 6 and 9ft tall. There are very few trees that grow alone or in small clusters.These plants had to adapt to the low amount of water so they now grow rapidly when the get water. The trees in the savanna grow long roots to get water deep underground.

The Biotic Factors

The mighty cheetah one of the many biotic factors of the Savanna. This is one of the mega-beast of the Savanna that is rivaled only by the hyena and lion. The Cheetah is the fastest animal alive on land. It's slender and slinky body design allows it to move fast and strike faster. It is a carnivore. Which means it eats other mammals and organisms, such as gazelles. Cheetahs are considered to be very deadly and fierce. They compete with lions and hyenas for territory and food. They usely aren't  succesful when going against a lion, though.

The sun is the beginning of the food web. It supply's energy for the plants, the plants then get eaten by herbivores such as the Gazelles, Baboons, and several types of insects. The second level consumers such as the cheetahs and hippos eat the first level consumers and then the second level consumers are eaten by the third level consumers such as the lion and hyenas.


Relationships Within The Biome

The Patas monkey is a medium to large sized species of Old World monkey that is found in the grasslands of Central Africa. Its's also known as the military monkey because of its long limbs its enable to run at fast speeds so they are prone to stealthy and quick on attack. The population in the past years is decreasing annually. Even though the population is decreasing their numbers are still substantial. Their numbers go down due to natural predators and human hunters. Humans also catch these animals to keep as pets and its estimated that over 1000 people are caught trying to catch the Patas monkey each year.

There are many different types of relationships and pairs in the Savanna biome. They include everything from mutualism and parasitism to predation and competition.

Lets talk about Mutualism. Mutualism is the relationship when 2 or more organisms work together and both benefit.

There is the relationship with termites and the Jackal Berry Tree. The relationship is where the heavy soils of the termite mounds provide a good source of moisture for the tree and in return the trees roots will provide protection for the termites from other predators.

Parasitism is a some what different story, though. In parasitism only one party of the pair benefits and the other slowly dies.

Elephants even though they are some of the most massive creatures on Earth they can still be a part of parasitism. Ticks and other blood sucking creatures will latch on to a elephants in places it can't reach and slowly suck away it's blood.

Predation is the next subject on our list. This is when one organism hunts and kills another.

One of the most iconic types of predation on this Earth is the lion and the Gazelle. Lion gets hungry and the Gazelle is a smaller, weaker prey thats ripe for the taking.

The last type of relationship is competition. There is competition all over the Savanna with animals fighting for water, food, and territory.

Lions and hyenas sound familiar? Well good if so. Lions and hyenas are two of the most common groups to fight in the Savanna with resources coming short they must fight each other to survive.
