Essay Example on Biodiversity
Ecosystem is a system formed by the interaction of all living organisms with each other and with the physical elements of the environment. The vulnerability of an ecosystem can be determined through the examination of its location, biodiversity, extent and linkages. The vulnerability of the ecosystem is closely linked with the effectiveness of the functioning and the diversity of the ecosystem. The resilience of an ecosystem is also important when looking at the survival of ecosystems. Resilience is a measure of the ability of an ecosystem to adapt to a changing function and structure following an episode of natural or human induced stress.
The biophysical interactions between the hydrosphere, lithosphere, atmosphere and biosphere lead to diverse ecosystems. Through the interaction of the three nonliving spheres, the hydrosphere, lithosphere and atmosphere a variety of different conditions are created for the biosphere. Location of a ecosystem determines the characteristics of the nonliving spheres it is through their interaction that the foundations of an ecosystem are made. For example deserts are usually located between 20 and 30 degrees north and south of the equator. In these locations we find that the interaction between the hydrosphere and atmosphere lead to dry and extreme temperatures. The sandy soils in the desert mean water drains quickly leaving no water. The lack of water in these areas means there is no precipitation. Therefore there are no clouds that hold warmth from the day through the night slightly. Water also acts as a moderator of temperature as it warms and cools slowly, as there is very little water the desert has high daytime temperatures and cold nights. Due to the hardy climate there is little biodiversity in the desert. Plants and organisms must adapt to suit the conditions. Widely scattered shrubs and water conserving plants are found in these areas.
