Transcript of Savanna Biome Adaptations

Adaptations in the Savanna Biome By Connor Ferri and Rachel Forney Introduction General Adaptations Animals: Abotic Factors Plants Biotic Factors In a savanna, there are general
adaptations that equip animals the best.
These usually involve being able to
endure the drastic weather changes that
take place as the seasons change. Most animals can either burrow or
migrate to locate water. Plants can
develop symbiosis with the insects,
allowing them to survive most drastic
changes. Although, not all organisms
adhere to these general adaptations. Animals must be equipped to survive the drastic weather changes; intense heat, rain, and drought constantly plague the savanna biome. Some animals migrate in order to survive the lack of food in the dry season. Animals like mice protect themselves with camouflage. Most animals that are prey are equipped to run very quickly. A few animals are nocturnal, allowing them to roam at night when it is “safer”. Also, animals like the Indian burrowing gerbil dig burrows that allow them to be protected. Likewise to animals, plants need to survive the seasons, as they change quickly and on a large scale. Most adaptations that plants possess are symbiosis with the residential insects. The rain is a major factor. It rains in a savanna twenty to sixty inches a year. Man-made structures can harm the land and the animals living on the land. When the sun is out, it parches the soil immensely, so it makes it more difficult for the people and animals that live there. People create the savannas themselves (for the most part), so they greatly impact the savanna biome. Also, insects also fertilize the soil and pollinate the few plants that thrive in the savanna. Thirdly, animals such as the elephant impact it greatly due to their stamping on the land, thus smoothing the bland terrain of a savanna. Symbiotic Adaptations Non-poisonous acacias are symbiotic with ants, because they give the ants sugar-water in exchange for the ants’ defense. Fungi rely on insects to provide nutrients to their roots. Insect-plant relationships are more common than symbiosis among vertebrates and other organisms, as plants and insects have co-evolved with each other. Limiting Factors
On land, the limiting factors can be temperature, water, light, competition, and soil, since all organisms have different requirements. If the temperature were to be extremely high for a period of time, some plants would not grow, forcing herbivores to find a different source of food, and perhaps causing them to perish. Ecological Concerns Savannas are mainly
created by humans,
as savannas can be
formed by the burning
of woodland. Although,
there are ecological concerns.
These are: poaching, hunting,
overgrazing, and destruction
of land. Relationships:
In biomes, animals have relationships connecting all forms of life. A few examples are predator-prey relationships and competition between species or animals of the same species.
Predator-Prey-
Lion-zebra
Dingo-kangaroo
Hyena- young cheetahs
African wild dogs- gazelles
Jackals- small vertebrates

Competition-
Territorial fights between large animals like lions and rhinoceros.
Competitions between animals from the same species to become the dominant or alpha animals. Image from:http://a66c7b.medialib.glogster.com/media/8f/8f6975d89c1b7112cf59b2b6c6e02bd0001edd43474a68546648e3acbd9b0b42/savanna-food-web-gif Food Web
