Biosphere is defined as that part of the earth and atmosphere in which many smaller ecosystems exist and operate. Three main subdivisions of the biosphere are lithosphere (solid matter); hydrosphere (liquid matter), and atmosphere or the gaseous envelope of the earth which extends up to a height of 22.5 km. The area of contact and interaction between these components is really important for life, for it is here that the entire life is confined and the basic processes of life like photosynthesis and respiration occur.

Living organisms are, mostly, confined to the parts of biosphere that receive solar radiation during the day. As stated above this includes atmosphere, the surface of land, the few meters of soil and the upper layers of water of oceans, lakes and rivers. The illuminated zone may be a few centimeters in turbid water of a river, and up to about 100 meters in clearest part of an ocean. In the ocean, the biosphere does not end where light ceases as gravity enables the energy flow to continue downward, since fecal pellets, cast skins and organisms dead and alive are always falling from the illuminated regions into the depths.

In addition to the extension of the biosphere downwards, there is a limited extension upwards also. On very high mountains, like Himalayas, the limit above which chlorophyll-bearing plants cannot live appears to be about 6,200 meters.

In simple words, biosphere can be viewed as the part of the earth consisting of oceans and the surface of the continents, together with the adjacent atmosphere (i.e. the troposphere). However, polar ice caps and the higher mountains slopes above the snow line are known as parabiosphere.

Since living organisms require inorganic metabolites from each of the subdivision of the biosphere, water from the hydrosphere, mineral from lithosphere and chemical elements from atmosphere, a brief discussion…...

Affect Humans Have on the Biosphere

...The biosphere is the region of the surface and atmosphere of the earth (or another planet) occupied by living organisms. It contains all the living things in the world: plants, animals and bacteria. It includes other layers of the atmosphere which are called the lithosphere, the troposphere and the hydrosphere. The lithosphere is the other region of the earth, the troposphere is the lower region of the atmosphere and the hydrosphere is the region of lakes, oceans, streams, ice and clouds that make up earth's water resources. There are over 30 millions species on this region of the planet, and the number of different organisms in an ecosystem is called biodiversity. The more biodiversity the more stable the ecosystem is.But it is still inevitable for each and every organism to adapt to their surroundings and even change it at times. But the biosphere never remains the same, no matter what. And the effects can either be negative or positive. The top species on the biosphere are humans, and they affect the area in both good and bad ways. Humans are the only species that make their ecosystem adapt to them instead of the other way around. This is why they have the most effect on the biosphere. Some things humans have done that improves the condition of the biosphere would be selective breeding. By putting the best of the best together, which normally cannot occur in nature naturally, this gives species a better opportunity to survive. In regards to crops, this allows them to......

Study of the Earth

...known as: the Lithosphere, the Biosphere, the Atmosphere, and the Hydrosphere. Each of these elements performs a certain function that is dependent on the other. The Lithosphere is the Earth’s outermost rocker layer. The Biosphere consists of recently decayed and living organisms on Earth’s surface. The Atmosphere is the gases that surround the Earth. The Hydrosphere contains all of the earth’s water and ice, above and below the surface. Losing any of these systems would have a depleting effect on the earth as we know it. There is a cycle to how these systems work, plants gain nutrients from the lithosphere and then these nutrients are incorporated back into the biosphere. When the plants die some of the material left behind is released into the atmosphere and the rest goes back into the lithosphere. Each element provides what is needed to continue the cycle and the cycle is a constant. People depend on each subsystem in the same way that the earth depends on these systems to continue. The lithosphere is important because “There are high mountains ranges like the Rockies and Andes, huge plains like those in Texas, Iowa and Brazil, and the deep valleys of the ocean floor .We walk and climb on this part of the lithosphere (Wheeling Jesuit University, 2005).” The biosphere is important because it contains the environment that a person lies in. “The biosphere is as important as life itself because it is all of life. Without the biosphere, the Earth would be a......

The Importance of Prokaryotes

...‘Not only do Prokaryotes have a wide range of metabolic activities crucial for maintaining the biosphere, they also exert significant impacts on human life’ discuss this statement fully using named examples. Prokaryotes are unicellular microorganisms without a nucleus; they are divided into two groups’ Eubacteria and Archaebacteria. These microorganisms are very small and invisible and are known as the most dominant species on the earth’s biosphere as they are found almost everywhere on earth, they are predominately, found in our body’s immune system, and they are mainly responsible for the decomposition of dead matter which in return benefits both plants and animals. They are found in the air that we breathe, in the food that we eat, in deep seas, in cold and hot temperatures, sea corals, in salt water, fertile soils and in short, they are so diverse in their form of habitation and adaptation, as different types of bacteria adapt to different types of environments in different forms of life. However, bacteria are grouped according to their uniqueness, features, structure, functions, and contribution to human life. Prokaryotes are so beneficial to us because they act as defences to protect us from various diseases. The essay will examine the significant impact of prokaryotes to human life. The word bacteria may be frightening to most of us; in many cases it is often associated with many negative and harmful aspects such as infectious diseases, dental decay, mould and...

Systems Thinking Approach as a Unique Tool for Sustainabletourism Development: a Case Study in the Cat Ba Biosphere Reserve of Vietnam

...SYSTEMS THINKING APPROACH AS A UNIQUE TOOL FOR SUSTAINABLE TOURISM DEVELOPMENT: A CASE STUDY IN THE CAT BA BIOSPHERE RESERVE OF VIETNAM Thanh Van Mai Bosch O.J.H School of Integrative Systems, The University of Queensland, QLD 4343, Australia Corresponding author (thanh.mai@uqconnect.edu.au) ABSTRACT Tourism is not simply an industry, but is an open, dynamic and complex system. The system consists of many interacting components and involves many different stakeholders. The development of tourism in a sustainable way impinges on and is subject to many factors. The limitation of traditional approaches to tourism research has become evidently in many cases. These approaches have usually looked at a particular issue or issues of the whole tourism picture. As a result, it has become difficult to manage tourism toward sustainability. This paper provides an overview of the systems thinking approach and its application in the study of the tourism system in the Cat Ba Biosphere Reserve of Vietnam. This study shows that systems thinking has proved to be an effective and powerful tool to explain the complexities of the tourism system. It has helped to simplify, clarify and integrate isolated problems associated with the industry, and provided a mechanism for group learning and decision making to achieve desirable outcomes. The paper proposes systems thinking be used as an appropriate tool for sustainable tourism development. Key words: complexity, dynamics, sustainability, systems......

O'Reilly Auto Parts Stakeholder Analysis

...subordinate’s obtainment of benefit or burden. Generally corporations focus on its primary stakeholders because they are the most noticeable and affected. However, it is myopic for a corporation to ignore or act in reluctance to its secondary stakeholders in naivety of the actual ripple that its action may cause. This is why stakeholder consideration and action is becoming a more ascendant quality of corporations. The analysis of four O’Reilly Auto Parts stakeholders will be discussed in this paper, each with its own synopsis of this corporations attempt to perpetuate its positive influence, and/or its failure to do so in particular areas. The stakeholders analyzed are customers, a primary stakeholder, and future generations and Earth’s biosphere, which are both secondary stakeholders. Primary Stakeholder: Customers Positives: Customer Stakeholder The customer is perhaps the most salient stakeholder. Providing the upmost care to the customer ensures lucrative sustainability of any retail sales corporation. O’Reilly Auto Parts has focused the majority of its efforts on the customer. Embedded in the culture is a pledge to provide optimal customer service (“The O’Reilly Culture”, n.d.). One way that O’Reilly Auto Parts attempts to execute this cultural goal is through the “never say no” challenge in which O’Reilly encourages all employees to never tell a customer they cannot find an auto part, even if it is not housed with one of their suppliers. The part must be somewhere......

Biology- Phototsynthesis

...Institution: Course: Name: Date: The author of the article " When Did Photosynthesis Emerge on Earth?” is David J. Des Marais. The author examines the period when photosynthesis emerged and the issues surrounding its emergence in our biosphere. The author looks at the historical and evolutionary evidence to advance the topic of the emergence of photosynthesis. The article is majorly based on the biosphere changes and the changes in the oxygen levels and the metamorphosis of sedimentary rocks to illustrate the sequence of biochemical records and trends. In the early Earth’s history photosynthesis has highly evolved. Also through the rapidity of its emergence has suggested that there was no existence of flukes and it could also on other worlds also (Des Marais, 2000). The question on when did photosynthesis take its place in the place Earth is an issue which has been researched widely in order to unearth the many unknown mysteries. Probably life is thought to have begun early the history of the Earth, perhaps more than 3800 years ago and through the years it has received a lot of sophistication in terms of metabolism. Great developments of biomolecules and key pathways reveal a great deal of evolutional innovations in the field of photosynthesis. A sequence of genes’ information has been used in the analysis of the major photosynthetic bacteria. Also the molecular origins of the major photosynthetic bacteria has been clarified to a great extent...

...circulates through the atmosphere, biosphere, oceans, and crust. This model is similar to ones presented by the Intergovernmental Panel on Climate Change (IPCC). It allows you to experiment with how human input to the cycle might change global outcomes to the year 2100 and beyond. One particularly relevant human impact is the increase in atmospheric CO2 levels. Between the years 1850 and 2015, atmospheric concentrations have risen from 290 parts per million (ppm) to over 400 ppm - a level higher than any known on Earth in more than 30 million years (see Unit 12 to find out how scientists measure ancient atmospheric carbon levels). Using the simulator, you will experiment with the human factors that contribute to this rise and explore how different inputs to the carbon cycle might affect the concentrations of the greenhouse gas CO2.
