The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry. 1. whats an example of a predator of a zebra? 3. separately explain predator- prey relationships and give three is an animal (organism) that gets its energy from eating other animals or Tornado in a Grassland Biome. There are many types of predators in the African Grasslands but here are some well-known predators in the habitat 1. Lion Food: Zebra, Bird, Gazelle 2. Cheetah.

The types of grasses present depend on the climate and location of the grassland, but all grasses have some basic characteristics in common. Grasses are well adapted to live in regions prone to drought and fire.

The long, narrow leaves of grass lose water less rapidly than broad-leafed plants. The silica present in the leaves of many grasses makes them strong enough to grow tall and maximize exposure to sunlight. The plants store much of their energy underground in their rhizomes and root system, so when leaves are killed by fires or predation, the plants can easily send up new growth.

What Kinds of Animals Live in Temperate Grasslands?

Invertebrates Numerous insects and other invertebrates live in grasslands. Some of the insects, such as grasshoppers, locusts and caterpillars, consume the grasses and act as grazers. Others, such as earthworms, serve crucial underground roles, helping to decompose organic matter and maintaining soil health.

Invertebrates also provide an important food source for the many bird species that inhabit grasslands. Sciencing Video Vault Grazers Some types of animals are specially adapted to consume hard-to-digest grass leaves.

Grasslands represent an ecological relationship between grasses and grazing animals. Whether the animals are wildebeest and zebras or bison and elk, the grazing herds help shape grasslands. Once the seeds have been harvested and planted, a restored prairie needs maintenance. Most restored prairies are burned periodically, a practice known as prescribed burning, to kill shrubs and trees that would otherwise move the prairie to forest.

An intact natural ecosystem is often very resistant to invasive species, so once restored the prairie is relatively stable as long as it gets its fire. Because some of these restored prairies are close to communities where the smoke and danger of the fires burning houses are a concern some prairie managers are looking at alternative methods such as mowing.

Whether fire or mowing is used, care must be taken to time the event so that it doesn't cause disruption to key species in the ecosystem. For instance, you wouldn't want to do a burn when ground-nesting birds are on their nests. With its high top speed several sources list about 70 mph kph it can catch just about any other animal; however it can't sustain this speed for long. It preys primarily on smaller antelopes and gazelles.

Cheetahs are critically endangered. The lion below left is not as fast, but it can take down larger prey, particularly when it works with other lions. Even so, much of a lion's diet can come from scavenging the kills of other creatures. Adult elephants above right are pretty much immune from predation, and because of their social structure, the young are pretty well protected, too. For a predator to approach a young elephant it would normally have to fight its way through the mother and a few aunts or sisters, and perhaps even a bull or two.

Elephants can also have a tremendous impact literally on the environment, as heavily trod areas such as near a water hole can become devoid of plant life.

The ostrich below is native to Africa. The other large ratites flightless birds of the southern hemisphere are the rhea South America and Emu Australia as well as the smaller kiwis and cassowariesall apparently descended from a common ancestor that lived while those continents were still joined about MYA million years agoalthough some modern DNA evidence sheds doubt on this.

These birds are mostly herbivorous, focusing particularly on seeds, although insects and small animals are also eaten. The two African species are the most grassland-loving species, and they each have a distinct ecological role. The black rhino above has a prehensile upper lip that it uses to browse pick off leaves from low-growing plants.

There are about 3, of these rhinos left in the wild. The white rhino right and below is more common about 12, individuals and has a wider lip. In fact, the name "white rhino" probably is a mistranslation of the Boer word "whit" which means wide and the black rhino was named just to contrast with the white, both species are gray.

The white rhino is a grazer. With both species feeding in different ways, it is possible for them to co-exist in an area.

A rhino can run about 30 miles an hour, and in contrast to the impression left by a car commercial, they can turn on a dime. Their thick hides help armor them, and the horns make a formidable defense and as the photo below shows, sneaking up behind a rhino won't do you much good either. Rhinos have an excellent sense of hearing note the ears, which can swivel to listen all around the animal and smell.

They've taken a rap for having poor eyesight, but that is probably a relative thing. The Bobwhite Quail consumes seeds and insects and lives mostly on the ground. The Cattle Egret is an interesting story. In its native Africa, this bird follows large herds of mammals, feeding on the insects disturbed by the herbivores.

They apparently crossed the ocean from Africa to South America in the late 's and reached the US by the 's.

Wherever they end up, their basic habit of following herbivores usually cows remains, but I have seen them in Florida following tractors mowing the grass along highways. The Killdeer left is normally dependent on rivers for its nesting ground, as they prefer to nest on open gravel areas, and the banks of a river after a spring flood fit this bill.

Closely related to various shorebirds, the killdeer follows the general killdeer habit of feeding on invertebrates gleaned from the ground.

Humans have made the killdeer's life easier, with our tendency to build gravel roads and even put gravel on their roofs. This has allowed these birds to make further inroads into grassland areas as opposed to the areas right along rivers. The Sandhill Crane is a large, majestic bird that feeds on insects and other small animals, as well as grains and other vegetable matter. Like the killdeer, the cranes rely on rivers as a conduit into the middle of areas like grasslands.

The picture below of the Ladybird Beetle is mostly for show. Larvae of these beetles feed on aphids which in turn feed on the grassland plants. Przewalski's horse Equus caballus przewalskiiThe Wilds, Ohio. Horses of all types are excellent examples of grassland animals.

Strong runners, they are able to kick, bite, stomp and otherwise trample predators; in addition they often live in herds which increases their ability to deal with predators. The inset picture here has been emailed all over the internet and appears on a number of websites, so I don't feel too bad in blatantly stealing it to make the point here. That is a mule, and it has picked up and is swinging a mountain lion.

Many of the stories accompanying the photos around the internet claim the mule killed the lion; most of the commentary seems to indicate that while this is possible in this case the lion was already dead. The point, of course, is that a horse isn't as helpless as it might first appear. Most "wild" horses around the world lower right are actually feral, that is they are descendents of domesticated horses which escaped from captivity.

Still, wild horses exist in the world - barely. Przewalski's horse was briefly extirpated from the wild but has been reintroduced from captive but undomesticated stock. In fact, the captive stock had at one point diminished to 13 individuals; all of the existing Przewalski's horses are descendents from them. Zebras, of course are cogeners with the horse, Equus caballus, Przewalski's horses are a subspecies of the modern horse and its only living wild ancestor. Another cogeneric horse is the Persian Onager abovewhich is also critically endangered.
