Blog #7 Biomes




Biomes or Ecosystems are the climate conditions on the Earth that we live in. Communities of plants and animals along with soil organisms are examples of ecosystems. The ecosystem includes 



   both abiotic and biotic factors. To tell apart the different ecosystems scientist use the factors, latitude like artic, boreal,temperate and subtropical or tropical. Humidity is another factor that scientist use to determine different ecosystems like seasonal variation: rain fall, a dry summer, and a wet winter. Another variation that determines a different type of Ecosystem is elevation, increasing elevation causes distribution of habitat types that is similar to increasing latitude.  Ecosystem are commonly called a prairie, savanna, or forest. In the forest ecosystem a common sight would be the plants, shrubs, and grasses. Leafy greens are a common sight in the forest ecosystem that also include animals such as microbes that live in the soil. Some other inhabitants of the forest ecosystem are the insects and spiders that help the decomposers of the forest. The consumers that are herbivores like rabbits and deer, deer is a common sight in the forest and could be seen grazing on the lush grass of the forest ground or on the leaves of some of the trees.  Other animals are raccons, possums, and preditors like coyotes and bears. Other preditors include bobcats and lynx that prey on other animals such as omnivores and smaller meat eatting animlas. Compared to the ecosystem of the Savannas there are alot of contrast between the two ecosystems, Savannas and forests.


In the Savannas the type of plant life that could be found are shrubs and isolated trees that are unlike the plants of the forest where the tree growth crowd the land. The floor of the savanna's are covered with rolling grass that are somewhat semi dry from the warm temperature that stretches year round. The two seasons of the Savannas are winter and summer. The winters are a long dry season while opposite from it is a long wet season that is summer. The animals found in the Savanna's habitat are animals that can survive the Savanna's harsh climate amoung these are birds like shrikes, hornbills, grey louries and green pigeons. Other animals include flycatchers, the knysna, purple-crested louries, rollers and raptors. The larger animals include the well known lions, leopards, cheetahs, and elephants. In addition there are also buffalos, rhinos, and hippos. Then there are the tall giraffes, the striped zebras, gazelles, kudus, waterbucks, and oryxes. But these are only some of the many animals to be seen in the Savanna's.
