Desert Saguaro Cactus Scientific Name: Carnegiea gigantean Habitat: desert slopes and flats Range: Sonoran Desert Observations: The shape and appearance of the Saguaro Cactus is easily recognizable in countless movies set in the desert. The cactus is a producer‚ using photosynthesis to create its energy needs. Since it doesn’t have leaves‚ its photosynthesis takes place in the top layer of its green stem. The cactus uses a number of adaptations to survive in the dry desert conditions. They

Respiration & metabolism Photosynthesis: the process of converting light energy to chemical energy and storing it in the bonds of sugar. Respiration: the release of energy from food and it takes place in animal and plant cells. Combustion: the process in which a substance reacts with oxygen to give heat and light. 5.2.2.

Outline the relationship between climate and one or more biomes. (10 marks). One biome which is part of the cold zone of the Earth where the latitude of the sun is from 60-90° is Tundra. Tundra is a treeless‚ level‚ or gently undulating plain characteristic of the Artic and sub-Artic regions characterised by low temperatures and short growing seasons. The polar areas between 60 and 90° latitude receive less heat from solar radiation as the angle of the sun is at a much lower angle towards the ground

to Alaska? Well it’s a land of cold dark weather that doesn’t appeal to most‚ but Alaska has been a major topic to the government that affects me and you. The Alaska tundra has been in question to drill oil or to protect the precious environment there. Should the Alaska tundra be opened for oil drilling? II. Should the Alaska tundra be opened for oil drilling? III. I will analyze this controversy in terms of the following stock issues. A. Ill: Is there a problem with the American energy supply

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 3. Temperate deciduous forest 4. Scrub forest called chaparral in California) 5. Tropical thorn scrub and woodland (Dry forest) 6. Savanna 7. Temperate grassland 8. Desert (cold and hot) 9. Tropical

Russia has the humid continental climate‚ which is prevalent in all parts of the country except for the tundra and the extreme southeast. Most of Northern European Russia and Siberia has a subarctic climate‚ with extremely severe winters in the inner regions of Northeast Siberia‚ and more moderate elsewhere. The strips of land along the shore of the Arctic Ocean‚ as well as the Russian Arctic islands‚ have a polar climate. The coastal part of Krasnodar Krai on the Black Sea‚ most notably in Sochi

categories - natural causes and anthropogenic (man-made) causes. Natural Causes Natural causes of global warming include the release of methane gas from arctic tundra and wetlands‚ climate change‚ volcanoes etc. Methane‚ a greenhouse gas which traps the heat within the earth’s atmosphere‚ is let out in large quantities in the arctic tundra and wetlands. In case of volcanoes‚ when a volcano erupts‚ tons of ash is let out into the atmosphere. Even though nature contributes to global warming‚ this

Snowy Owls Snowy Owls 2012 Com156 12/9/2012 A snowy owl will live out the entire course of its life in the open artic in most cases‚ while others will migrate out of the arctic tundra. They will hunt‚ eat‚ mate‚ reproduce‚ and die where they reside. The largest bird in the artic‚ by a weight of up to six pounds‚ the snowy owl stands roughly two feet tall (National Georaphic). The snowy owl is a fearless hunter and strong protector. The snowy owls are diurnal‚ hunting mainly during the day

taken to preserve the unique biodiversity of the area‚ these include: eradicating rodents and feral cats and removing the quinine tree‚ which is one of the most serious alien plant invaders. The Arctic is an example of a biodiversity hotspot under threat by global warming. The tundra‚ with its rare arctic plant ecosystem‚ will shrink as rising sea levels are drowning coastal areas. Increased forest fires and insect infestations are expected to destroy
