Sahara desert General facts: Largest Desert in the world 10 percent of the African continent‚ 5000 years ago had a significantly larger mammal population‚ due to it getting dryer and over hunting in the last 100 years‚ the mammals are near extinction in the sahara. Intro: Definition of desert: “a region so arid because of little rainfall that it supports only sparse and widely spaced vegetation or no vegetation at all” Deserts cover about one fifth of our planet‚ and are caused by extremely

Tundra is the coldest of all the biomes‚ Tundra comes from the Finnish word tunturia‚ meaning treeless plain. It is noted for its frost-molded landscapes‚ extremely low temperatures‚ little precipitation‚ poor nutrients‚ and short growing seasons.A climate is a habitat around the world. The Tundra has snow everywhere and has very short growing seasons which means plants are hard to grow and farmers or whoever is planting crops need to plant early summer or fast enough before summer ends. The Tundra

Tundra Biome {draw:frame} {draw:frame} The arctic tundra can be found in the northern hemisphere‚ encircling the North Pole and extending to the coniferous forest of taiga. Some specific locations of the arctic tundra include Northern America (Northern Alaska‚ Canada‚ and Greenland)‚ Northern Europe (Scandinavia)‚ and Northern Asia (Siberia). The alpine tundra can be found in the mountains throughout the world at high altitudes where trees are unable to grow. They can be found in Northern

Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? In my own opinion No but as u read more about it some things need to be preserved. For instance animals help the crops of the foods that we eat. Snakes help to cure different diseases. Humans help the plants and animals to grow. The fact that human beings are a species means that they depend on many other species

Desert Marcus Green SCI/230 11/11/2012 Yasmin Henry Desert biomes can be defined as sandy regions that have very little rainfall as less than 50 cm a year with extreme temperatures and very scare vegetation. The fact that deserts are so dry the temperatures can change drastically‚ during the day temperatures can be as hot as 32 degrees Celsius‚ but at night temperatures can drop as low as -4 degrees Celsius because when the sun goes down there is no moisture in the air to trap the heat

to water-saturated soil. Some wetlands are inundated at all times‚ whereas others flood infrequently. Wetlands are home to a diverse community of invertebrates‚ which in turn support a wide variety of birds. Wetlands are among the most productive biomes on Earth. Their water-saturated soils favor the growth of plants such as floating pond lilies and emergent cattails‚ many sedges‚ tamarack‚ and black spruce‚ which have adaptations enabling them to grow in water or in soil that is periodically anaerobic

According to the text book‚ a biome is a large‚ relatively distinct terrestrial region with similar climate‚ soil‚ plants‚ and animals‚ regardless of where it occurs in the world. There are four aquatic biomes and nine major terrestrial biomes. The nine major terrestrial biomes are: tundra‚ boreal
