He claimed that each of the present continents was once joined together as part of a super continent called Pangea. He believed this because he saw that in certain areas continents would fit together for example the west coast of Africa fits together with the east coast of South America, therefore they must have moved apart from one central mass. Other evidence was shown to back up this theory such as the fact that glacier derived clays are found in all of the continents in Gondwana forming one half of Pangea, as one striations in rocks of Carboniferous age. Presently they cover half the globe but would form a reasonably sized polar ice cap if Wegener’s theory was true and the globe was reconstructed in his image of how it used to be. Despite Wegener having no concrete proof as to why this was the case his theory was proved to be accurate, physicists had believed that the earths crust was far from strong enough to be able to force itself apart.
How can this quote be related to the concept of the food web, or Trophic/energy pyramid? What is the implied warning from Mufusa? What could happen if this balance is not respected? Indicate a scene in the movie that is an example of this loss of balance. Mufasa is talking about the ecosystem.
Wegeners ideas were proved even further, increasing our knowledge of tectonic events. Sea floor spreading shows that rock is being both created and destroyed. In the 1950s and 1960s, ages of the ocean floor were measured. The surveys suggested that very young rocks, ageing less than 1 million years old, are found near ridges and older rocks, ageing over 200 million years, are found near the continents. Evidence of sea floor spreading can be found in the Atlantic, where it is believed that the North American and Eurasian plates are moving apart at a constructive plate margin.
Plants are the producers for an ecosystem. They photosynthesise carbon dioxide and water and produce energy in the form of carbohydrates and other molecules. Photosynthesis requires water, and plants gain water from the soil using mineral ions such as nitrate produced by the nitrifying bacteria. Hydrolysis of ATP releases energy for processes such as active transport of the nitrate ions (and others such as potassium etc) from the soil into root hair cells, a process that lowers water potential and is used to draw water into the plant from the soil. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.
The main theory of plate tectonics was first developed by a German called Alfred Wegener in 1912. He saw that the continents appeared to fit together like the pieces of a jigsaw, a good example of this is the African and South American coastlines. This would suggest that they were at one time in Earth’s history joined together as part of a super continent Pangaea, which separated forming Gondawanaland and Laurasia to the north of the planed. Later evidence was found to support this theory; fossilised remains of a dinosaur, called the mesosaurus, was found on the east coast of South America and the west coast of Africa around the country of Gabon. There were also the same fossilised pollen species and rock sediments on these coastlines.
The food web case study uses annotations that adequately provide models that depict the predator and prey relationship found in the ecological environment. This relationship is very competitive and discrete mathematics provides different assumptions and computational rules to maintain a natural balance. Competition within the food web describes the parameters needed for each element to exist and coexist within a given environment. These parameters consist of elements such as Ph balance, temperature (or climate), food availability, and so forth. For each animal or plant represented, these parameters provide a niche for survival in the ecological system of nature.
Plate Tectonics is the theory that explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates, and these move relative to one another creating boundaries at which plates converge, diverge and move past each other. As far back as 1620, Francis Bacon noticed that the west coast of Africa and the east coast of South America looked as if it would fit together. Between then and 1912 others identified further similarities but it was only that year when Alfred Wegener published a theory and subsequent evidence to explain why the earth appeared to be a huge jigsaw puzzle. He suggested that all continents were once a huge supercontinent, called Pangaea- which drifted apart.
There needs to be a better understanding on the interaction of the human body with dietary protein in food. Recommendations were taken from preliminary discussions, and the ones that were identified were
Brief description of Topic. This unit deals with the formation of the landscape of East Africa. The forces, which produce physical features, are of two types: internal forces and external forces. Earth movements e.g. folding, faulting, down warping and up warping, volcanicity and earthquakes have formed features on the landscape of E. Africa.
Tropical Savanna A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment. The climate and geography of a region determines what type of biome can exist in that region. Major biomes include deserts, forests, grasslands, tundra, and savanna. Each biome consists of many ecosystems whose communities have adapted to the small differences in climate and the environment inside the biome. Any change in one part of an environment, like an increase or decrease of a species of animal or plant, causes a ripple effect of change in through other parts of the environment.
