PLANTS: The savannah is dominated by grasses such as rhodes grass, red oats, star grass, lemongrass and some shrubs.
Researchers found that grasses have an advantage in very humid conditions because they can absorb water quickly and support high rates of photosynthesis, the process by which plants convert sunlight into energy.
The elephant adaptation that the shallow roots allow the elephant grass to absorb water very quickly. Elephant grass has hairy, coarse culms and sharp edges that deter predators from eating the plant. The sharp edges help protect the birds nesting in the grass from predators.
In the savannah there are many types of grasses such as B. Rhodes grass, red oat grass and lemongrass. The Bermuda grass that many plant in their lawns comes from the African savannah, as does the elephant grass, which can grow up to 3m tall.
Zebras eat a variety of plants such as star grass, red oats and other grasses.
Most of the savannah is covered with different types of grass, including lemon grass, rhodes grass, star grass and bermuda grass. There are also many trees scattered across the savannah. Some of these trees are the acacia tree, the baobab tree and the jackalberry tree.
They provide livestock of all kinds and other grazing animals with their staple food. Grasses also add variety and stability to the soil surface of the landscape, and they have amenities and ornamental uses.
Plants have many adaptations to survive the grassland biome. The plants have deep, spreading root systems that give them strength and moisture in times of drought. Most plants have long, narrow leaves that don’t need as much water. The grasses grow from below and grow close to the ground.
Some of the most common grasses include species of bluestem (Andropogon), straw grass (Hyparrhenia) and kangaroo grass (Themeda). In wetter savannas, Brachystegia trees grow over a 3 meter high understory of elephant grass (Pennisetum purpureum).
For trees, most savannah adaptations to drought are – long taproots to reach deep water tables, thick bark to withstand annual fires (hence palm trees are prominent in many areas), deciduous trees for avoidance of moisture loss during the dry season and use of the trunk as a water storage organ (as in the baobab tree).
Red Oat Tree: Adaptations: Red Oat Grass has some drought tolerance and can survive fires as its seeds are naturally buried 1 inch below the surface and are unaffected by fire. p>
Cenchrus purpureus, synonym Pennisetum purpureum, also known as napier grass, elephant grass or Uganda grass, is a species of perennial tropical grass native to the African grasslands. It has low water and nutrient requirements, allowing it to take advantage of otherwise uncultivated land.
Lemongrass has developed large stomata on both sides of the leaves. Also, it has evolved special guard cells to regulate water and gas exchange, and these guard cells open and close the stomata. These grasses have long taproots to reach deep water tables, making them drought tolerant.
Grasses of the savannah
Grasses are by far the most abundant plant species in the savannah. They define the ecosystem and represent nearly 75 species. Common crabgrass (Digitaria eriantha) is the most important forage grass of the African savanna.
A large proportion – from 15 percent to over 90 percent – is grass, which is tasty and digestible, especially when compared to the woody vegetation that dominates forest growth. Many shrubs and trees in savannas have leaves that are eaten by grazing mammals and invertebrates.
Star Grasses are well adapted to many soil types ranging from sand to clay. Star grasses prefer moist, well-drained, fertile soil. However, starfish grasses tolerate short periods (3-5 days) of surface water (1-2 inches) and perform well in these conditions.
No predator hunts lions to eat them; However, they do have some natural enemies, such as hyenas and cheetahs. Hyenas compete with lions for food and often attempt to steal their prey.
Zebras are consumers who only eat plants. (This means they are herbivores.) Zebras eat a variety of plants such as star grass, red oat, and other grasses.
Savanna biomes are fairly common, often alongside plains and desert biomes.
