5 Factors that might cause fluctuations in the amount of vegetation in a area and how this impacts the animals that eat the vegetation.
When people think of the American Prairie, they think of a dull, and grassy-full biome. But, the American Prairie is an extremely fascinating biome. At first glance, this grassy biome may look really dull and boring, but if you look deeper into it and feel nature playing its daily roles in this prairie around you, then you will see how unique this biome is.
Grasslands are characterized as lands dominated by grasses rather than large shrubs or trees. There are two main types of grasslands: temperate grasslands and savannah grasslands ("Types of Biomes", 2017). One major savanna grassland is located in Africa and takes up more than a third of the continent's land area. Others can be found in India, South America and Australia. If the grassland is prevented from developing into a forest by climatic conditions such as rainfall, it is termed as ‘climatic savannas’. If their characteristics are kept by soils, they are termed as ‘edaphic savannas’. These can occur on hills or ridges where the soil is shallow, or in valleys where clay soils become waterlogged in wet weather. Human activities such as farming
The common traits that all four land areas expressed on the survivorship curve were between type one, two and three. Most of the species found in the vegetable block, grazed and ungrazed pastures such as Vulpia are R selected. R selected are short lived, highly mobile, often density-independent and the survivorship is typically lower than K selected species (Parry, 1981). R selected are typically more frequent than K selected but are also unstable. The woodlot and some species in the ungrazed pasture are K selected species, such as Blackberry. These species are typically long lived, the mobility is often more sedentary, often density-dependent and the survivorship is typically medium to high (Parry, 1981). Shorter lived plants are

Explain how environmental factors (temperature, water availability, soils and topography) influence the yield of the food staple.
In 1988, a series of fires burned much of Yellowstone National Park (Klotzbach, Thayn 2014). Satellite images were used to measure light reflection, which were used to represent the growth and health of the trees after the fires (Klotzbach, Thayn, 2014). Lodgepole Pine, (Pinus contorta), was one of the species focused on since it is found in about 80% of the park (Turner et all, 1999). Satellite images were taken in late summer to early fall, on cloudless days (Klotzbach, Thayn, 2014). In areas that were only lightly burned, percentage coverage of Lodgepole pine returned to normal, before the fires, in 1991 (Turner et all, 1999). The seed density after the fires varied based on fire severity, areas with severe surface burns had little seed distribution at first, but increased substantially in 1990 (Turner et all, 1999). Areas that had
