Climate change is already hitting Africa hard however‚ the IPCC (International panel on climate change) have suggested that Africa will be getting even drier and continue to steadily warm like it has warmed by 0.5 degrees Celsius since 1900. Already being amongst the poorest countries of the world‚ many African economies are expected to suffer further drain as global warming continues to rise. Most African economies are heavily dependent on agriculture; reliable for their survival‚ selling cash

Hey there follow me around and you’ll be safe when you come to the arctic tundra. I am a Arctic fox one of the animals that eat other animals and let me tell you they fear me. I will go around and tell you everything you need to know. So you my friend are a new born Artic fox. Now first things first you need to know your surroundings it is always snowy and we are camouflaged with out fur so reax when someone comes by because they may not see you. The regular temperature is 10-20 degrees and really

The Tundra is the coldest and the rarest of all the biomes. The tundra contains many animals and plants that can be in the cold weather. The weather is about -30 degrees out there. Animals can survive out there because they have fur and fat to keep them warm. The plants live in the tundra because some plant can adapt there. The place where the tundra is located is the North Pole. The tundra is located at the top of the world‚ near the North Pole. It covers a fifth of the Earth’s surface . The

Week 13 Review Biomes 1. What is a biome? a. Large area of similarly adapted species 2. How are plants similar and different in the biome of two different locations? a. Plant species vary but plant for is similar 3. How does latitude influence biomes? a. Above 60o N latitude Artic b. Below 60o N latitude 4. How does continental placement influence biomes? a. Coastal areas more moderate temp fluctuations b. Interior areas more extreme temp fluctuations c. Areas behind mountains

BIOMES LAB BIOL 120 `` A biome is a major complex of similar communities. It is the largest ecological unit we recognize. Different books vary in the number of biomes they list. Temperature and precipitation are the two key factors that determine the different type biomes. Some books consider marine ecosystems and freshwater systems as biomes. Others break out wetlands as a biome. We will look at 10 terrestrial biomes: 1. Tundra (Arctic and alpine) 2. Boreal forest or taiga

TUNDRA CLIMATE The tundra biome is characterized by extremely cold temperatures and treeless‚ frozen landscapes. There are two types of tundra‚ the arctic tundra and the alpine tundra . ARCTIC TUNDRA The arctic tundra is located in the extreme northern hemisphere around the North Pole. This area experiences low amounts of precipitation and extremely cold temperatures for most of the year. The arctic tundra typically receives less than 10 inches of precipitation per year (mostly in the form of

tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons The Tundra Biome is one of the most unique Biomes in the world. Covering one tenth of the earth’s land area it is a substantial Biome. Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi‚ meaning treeless plain. It is noted for its frost-molded landscapes‚ extremely low temperatures‚ little precipitation‚ poor nutrients‚ and short growing seasons. Major problems With

tundra is an unusually cold and dry climate. Precipitation totals 6-10 inches of rain a year‚ which includes melted snow. This is almost as little as the world’s driest deserts. Coupled with strong and drying winds‚ the tundra is an extreme weather biome. The tundra seems like a wet and soggy place because the precipitation that falls evaporates slowly‚ and because of the poor drainage caused by the permafrost. You can find the tundra climate in Köppen’s E climate category. The Estands for ice climates

study of spatial distribution of species both past and present. 1939- FREDERIC CLEMENTS AND VICTOR SHELFORD introduced an approach that will combine plant and animal distribution in one classification system. They called these biotic components as BIOMES. It is important because it was able to illustrate the dependence of animals on plants. Why are there consistent
