Ecology
Ecology is a biology branch which focuses on examining living organisms in their environment. Ecologist study the inactions of organisms within their environment, including ecosystems, communities and populations that influence life on earth. Economist can see the interconnection of animal and plant populations shape physical environments and the interactions of the different species.(N/A, 2014)
The biota of earths process of biochemical's is four spheres which consist of atmosphere, hydrosphere, biosphere and lithosphere. These are driven by solar energy, decomposers, producers and the consumers that move materials in quantity. This cause inputs and outputs of
inorganic and organic nutrients The materials or compounds and elements found in all the spheres. Only in recent time have they began to understand the diversity roles of the biosphere. Each specie and species of a community contribute to the ecosystem. Ecosystems depend on chemical and physical conditions, along with the number communities and species of all the locations such as grasslands, forest and wetlands to name a few. The processes of the ecosystem and biodiversity is sensitive to the declines. Local biodiversity declines are more important than the declines globally. These changes in the biodiversity influence the process of the ecosystem. When the diversity that is local declines the production of plants may also decline and this brings variables into the ecosystem.( Naeem, Chapin III, Costanza, Ehrlich, Golley, Hooper, Lawton, ONeill, Mooney, Sala, Symstad, Tilman,1999)
The ecosystem has chemical cycles that contain both biotic and abiotic compounds known as biochemical cycles. The ecosystem has ...

Species diversity is the abundance and variety of the different organism types in areas in which they inhabit. In the same amount of area but in different locations there will be different species. This diversity can be measured many different ways and there is no on best method.
Ecosystem diversity covers a region and the habitats variety which occurs, this creates a mosaic type pattern in a landscape. An example would be an area of the habitats and the their variety the environmental parameters like salt and fresh water, rivers, estuaries, wetlands and grasslands. This diversity is hard to measure than the other two diversities because of the community boundaries, species associations and the elusive ecosystems.(N/A, 2008)
Purpose: The purpose of this lab is to investigate the various components of different ecosystems in a smaller representation and study the conditions required for the ecosystem’s sustainability as well as the connections between
(http://www.encyclopedia.com/doc/1O7-densityfrequencydominance.html) Biodiversity is the number of richness or the number of species in a local area. This happens when someone can look at a species, in order to indicate a degree of uncertainty. This can happen by calculating the number of species given, where the individual is picked at random from the community. In other words, if the diversity is high, then oneself will have a poorer chance of correctly calculating the species of the next individual picked at random.

Environmental Studies is the academic field, which systematically studies human interaction with the environment in which we live in. It is a broad field of study that includes the natural environment, built environment, and the sets of relationships between them. Environmental studies takes into account many different factors that help provide an enjoyable, fruitful way of life, such as national policies, politics, laws, economics, sociology and other social aspects, planning, pollution control, natural resources, and the interactions of human beings and nature.
There are many aspects to include when defining diversity. Diversity is understanding biological variations, space, social organization, communication, time and environmental control of a culture. The first aspect is understanding the different biological variations within different cultures of people. Biological variations include: body structure,

Connections: • Strand 6.4: Stability and Change in Ecosystems The study of ecosystems includes the interaction of organisms with each other and with the physical environment. Consistent interactions occur within and between species in various ecosystems as organisms obtain resources, change the environment, and are affected by the environment. This influences the flow of energy through an ecosystem,
Scientists have begun to say that we have to do more to protect our ecosystem, because our very existence is depending upon it. When the ecosystem is not functioning properly the continuation of plant, animal and human life ecosystems would be impossible. Life cycles can not function without ecosystems. The ecosystem provides us with clean air, water, habitats for fish and other services. They also aid in the mod...
No one really quite understands what it takes to be an Environmental Scientist. Environmental Science is a broad type of science. It may involve nature, animals, or anything in between. Some subsections of it can consist of pollution management, natural resources, or wildlife management. Also, there are types of programs for protecting the environment such as scientific, behavioral, economic, and political.(apu.apus.edu) Most environmental scientist go into the scientific field of it, but there are some that go in for other reasons. The second most popular is behavioral.
The degradation of ecosystems and loss of biodiversity is increasing at an alarming rate every year. Humans are certainly not the only reason for this, but they are the main contributors. The well-being of ecosystems affects our everyday lives - consumption and consumerism depend on natural resources. Everything humans use is derived from them, in seemingly indirect and direct ways. Yet despite the fact that humans are destroying the environment, many continue to and neglect to take important measures to protect it.
Ecology is the clinical research of interactions of organisms with one another and with the chemical and physical environment. Research studies carried out within the clinical discipline of ecology might for that reason focus on one or more various levels: on populations of a single types, on a communicating neighborhood including populations of lots of types, on the motion of matter and energy through a neighborhood within and environment, on big scale procedures within a biome, or on worldwide patterns within the
The branch of science that deals with how living things, including humans, are related to their surroundings is called ecology . The Earth supports some 5 million species of plants, animals, and microorganisms. These interact and influence their surroundings, forming a vast network of interrelated environmental systems called ecosystems. The arctic tundra is an ecosystem and so is a Brazilian rain forest. The islands of Hawaii are a relatively isolated ecosystem. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Complex ecosystems are able to compensate for changes caused by weather or intrusions from migrating animals and are therefore usually said to be more stable than simple ecosystems. A field of corn has only one dominant species, the corn plant, and is a very simple ecosystem. It is easily destroyed by drought, insects, disease, or overuse. A forest may remain relatively unchanged by weather that would destroy a nearby field of corn, because the forest is characterized by greater diversity of plants and animals. Its complexity gives it stability.
One of the reasons for loss in biodiversity is alteration of habitats. A habitat is the natural environment in which a species of living organism lives. If the habitat of a species is changed, it will cause the species to die or migrate to other places where it can find its natural habitat. There are many ways in which the habitat of plants and animals can be altered. One of them is land use changes. Since the beginning of human life, human beings have been changing land use for farming. Large areas of forests have been cleared by humans to increase the area of farming to satisfy their growing needs. Many biodiversity-rich landscape characteristics have been lost due to intensive farming (Young, Richards, Fischer, Halada, Kull, Kuzniar, Tartes, Uzunov & Watt, 2007). For example, traditional farming was replaced by private farms in Europe after the First World War causing an immense change in land use patterns. Another major proble...
Environmental studies is a paramount field to focus on for both the present day and the future. This field of studies pertains to all people, animals, plants, and biomes around the world. Environmental Studying is important because it is only by understands the environmental processes that we can begin to take the steps necessary to correct the on-going damage that is occurring, and ultimately protect and sustain life on the planet. Unless steps are taken to try and abate and control environmental problems, which are often human-generated or exacerbated, then the environmental that we live in will continue to deteriorate. There is no life without protecting the source that sustains us. Even though I have only been alive for seventeen years, it has been long enough to see many negative environmental changes. Since I was born that population has grown by over one billion people causing deforestation, loss of wildlife, increased pollution to both air and water, and even superbugs. However, I have also been able to see extremely positive results such as an increase in the research and implementation of renewable resources. The reason I am so motivated to study environmental science is because I know that change is possible. Those who study environmental science and study have the ability to help reduce, and possible reserve, some of the damage that has been done to the environment while at the same time, helping to advance the well-being of our fellow humans.
