Savannah biomes have various types of soil that are found across its land. Even though savannahs have a wide range of various types of soil it is not suitable for farming. In the savannah biome all animals and plants are extremely dependent on each other for food supply. If one species of animals were to be removed, the entire ecosystem would be altered causing a major break down of the food chain or cycle.
Water in savannah biomes is very scares especially when it isn’t a wet season, some animals go through a long period of time without water during a dry season that they barely make it till a wet season ,because of dehydration. The savannah biome receives about 59 inches of rain, majority of this occurs during the wet season. Plants that grow in savannahs are highly specialized to grow in this environment for a long period of droughts, because they have long tap roots that can reach the deep water tables.
Most African cultures in Africa harvest plants in savannahs for traditional medicines for their own uses. Fuel wood is also found in savannahs for villages around to use as a cooking source or for other uses. There are some cultures that find materials to make clothing.
Most savannahs provide employment for veterinarians, hunters, rangers ect. Places like the Kruger national park supply jobs and helps the country to gain more tourists.
The savannah is a well known place where we mostly find the big five
The savannah biome is mostly made up of grass but there are a few trees and because of the availability of grass in the savannah,there are many grazing animals who take advantage of this abundant food supply,so baisically the savannah provides food for most animals yhat eat grass and all like zebras,giraffes and buffalo’s
The savannah is also rich witg herbivores such as elephants,zebras which can automatically become food to animals like lions tigers and all and mostly all the animals and plants are extremely dependent upon each other for food and supply
As it comes to the climate in the savannah it is very important because if the rainfall decreases or the temperature increases,the animals and plants will not be able to continue to survive and the savannah emails warm all the year long and during rainy seasons or wet seasons,the temperature is more pleasant with an average of 60 degrees Celsius
One of the most popular disease at the savannah is malaria which is spread by the mosquitoes and the disease can be very fatal if one doesn’t receive treatment in time. So if you at the savannah one can avoid getting malaria by wearing long clothes and all.
Soil formation and Nutrient Cycling in the Savannah
The savannah Biome is the largest biome in southern Africa occupying 46% of its area and over one third the area of South Africa .Its well developed over the low veld and Kalahari region of South Africa and is also the dominant vegetation in Botswana Namibia and Zimbabwe Enviromental factors of the biome are complex altitude ranges from sea level 2000m rainfall varies from 235 to 1000mm per year frost may occur from 0 to 120 days per year and almost every major geological and soil type occurs within the biome. The cycling of nutrients is what helps us define an ecosystem if there’s anything that separates a habitat from an ecosystem it’s the fact that most nutrients and energy are well recycled within ecosystem whist habitats once you ignore solar inputs, often have large in and out flows of nutrients and energy. Nutrients are extremely important in shaping savannah habitats, both at large scales and fine scale. The large scale pattern of nutrient availability lead to different vegetation types in different areas. The most important nutrients cyclers of the savannah the termites in the middle of the dry season there are lots of an eaten grass in the foreground and background around the mound. By gathering up bits of vegetation in one spot they concentrate nutrients at this spot grass growing there is richer and better food than grass growing further away animals know how nutrient rich their food is. The rare locations of mineral deposits utilised by a range of wildlife most famously by elephants. In some places they have dug caves over 160m deep into mountain sides in search of nutrients
