Ecology is the study of plants and animals and the certain environment that they live in plus what they do that is what I will be covering the following. The place that the organisms live is in the biosphere and there are abiotic factors which are the nonliving parts of an organism's environment and there ecology essay biotic factors which are the living factors in an organism's environment. A habitat is where organisms live, but an ecosystem is the interactions between organisms and the biotic factors plus. Mayer, the author does an exceptional work in recognizing the main factors and how, throughout time, they have evolved into a new idea for the medical geography.

original Greek "oikos" means, "house". So ecology is "the study of the house" the place where you ecology essay, or the ecology essay which technically includes all those factors, both nonliving and living, that affect an organism. Ecology then is the study of the interactions of organisms in their environment includes both the living biotic and physical abiotic factors of the environment. It's also the science, ecology essay, which formulates and tests hypotheses about environment, ecology essay. Ecology is the relationships, identification. Introduction Social ecology is the conceptual principles for knowing the outcomes and relations of the many diverse individual and environmental factors. Social ecology is defined as the study of people within an environment, which have influence on one another.

Factors of social ecology may include the infirmities of age, an increase of population, natural disasters. assumptions similar to those that govern the natural world. Specifically, this theory holds ecology essay notion that the overall structure of cities is based on the struggle for limited land ecology essay. Over time, urban ecology has evolved to include a wider spectrum where it now generally refers to a subsection of ecology that studies the interactions among human beings, plants, and animals within an urban and metropolitan area, as well as the effects that urbanization have on natural ecosystems and biodiversity within.

It is very common to talk about ecology of the world. But what does ecology mean? Ecology is the science which studies the relationship between all forms of life in our planet and the environment. Long time ago, ecology essay, in the ancient times people lived in harmony with the environment. They lived using what Earth gave them. It seemed for people that the resources of nature ecology essay no limit. With the industrial. Ecology, or in Greek translation "study home", is the study of the interactions of organisms between it's enviornment.

While biosphere means the whole worlds ecosystem. Why are these terms so important? The reason why they are important to everything on Earth because they hold and shape all organisms that live within them. Without organisms animals, plants, and everything that we know would never be able to survive. If ecology wasn't organized and delicate, the system wouldn't be the same to the, ecology essay.

What is an active eco-system? Ecology is defined as the scientific study of the interactions of living organisms with each other and with both their physical and chemical environment. It examines the entire scope of life from the microscopic organisms such as bacteria to mega processes that traverse the whole planet. Ecologists analyze many different and complex relations among the many lives on the earth. The areas of interest to an ecologist include diversity. The theory of Ecology is the study of relationships between organisms and the environment within an ecosystem.

Ecology is everything to the human population. It covers a broad ecology essay including speciation and population dynamics.

The history of ecological thought, like that of the field of conservation biology, traces back several centuries. The earliest formal practice ofecological research on the relationship between organisms and their environment dates to the botanist Alexander von Humboldt, who in the early 19th century, described the relationship between plant distributions and regional climates.

As developments in ecology continued over the next several decades, advances were made in the understanding of global bio-geochemical cycles e. Succession is the process by which an ecological community progresses over time from an initial, simple state to a latter, complex state as the systemapproacheda stable equilibrium sometimes called homeostasis. The change in the overall ecological community over time reflects, among other things, theloss and gain of individual species. A disturbance; such as wind damage, openingupof aforestgap by treefall, plowing of a field, creation of a patch by waves in an inter-tidal zone, or a rainfall event that creates an ephemeral pool, creates new localized habitats for different species to colonize and exploit.

According to successional theory , early colonizers or invaders tend to be those that are best adapted to reproduce rapidly and quickly colonize the new habitat, and typically have high reproductive rates and small life spans. Such species are often referred to as r-strategists. Such slow-growing species are often referred to as K-strategists. The role ofhumansin ecological processes was viewedina negative light, as interfering with the processes of natural succession. The ecologist Arthur Tansley often acknowledged the significance of the work of Cowles and Clements, and yet, disagreed with the Clementsian notion of a monoclimax. He argued instead that environmental gradients and varying disturbance regimes within aclimaticzone meant that later successional stages would support not a single but multiple climax communities.

He took further issue with the uniformly negative portrayal of human agency in ecological dynamics, suggesting instead that human-nature interactions gave rise to anthropogenic climax communities suchas agro-ecosystems. In , Tansley introduced the term ecosystem to refer to the interacting system formed by biota with its environment. Hismodels were strongly influenced by emerging ideas about systems and fields in physicsatthattime, and suggested that organisms couldbestbestudied as interacting components of bio physical systems.

The ecosystem concept was subsequently adopted and elaborated by Eugene Odum, often referred to as the father of modern ecology. In , Eugene Odum and his brother, Howard Odum, jointly authored the first definitive textbook on modern ecology, established ecology as a bona fide academic discipline and educated the first generations of ecosystem ecologists in North America. Odum applied the strategic ecosystem approach to ecological communities in their successional paths, theorizing that older, more advanced communities should contribute to overall ecosystem stability, or homeostasis, securing protection against environmental disturbances. Other developments preceded and paralleled the riseoftheecosystem concept in ecology.

Charles Eltonexpanded on the ecological form structure and function that exists at any given time in a successional sequence, rather than the process of change over time. In , Elton proposed a set of principles in his text Animal Ecology that aimed to explain an organization of ecological communities focused upon the food chain and laid the foundation forpresent thinking on trophic interactions. Elton also proposed the pyramidal structure of the food chain in considering how the size and populations of a species as food or consumer relate to its position in the pyramid e. Finally, Eltonproposed the idea of the ecological niche as the function of a species in a community, maintaining that no two species in a community could occupy the exact same niche because of competitive exclusion.

Elton, Tansley, the Odums and other ecologists influenced by developments in physics turned to the second law of thermodynamics to focus on the flow of materials e. There were attempts to merge lessons from trophic structureand ecosystem function. For instance, Raymond Lindeman and others studied the productivity of each trophic level and the efficiency of the transfer of energy from one level to the next in order to understand the functioning of entire ecosystems. Ecosystem function began to be quantified and measured in energy units.

For instance, the net primary productivity NPP of diverse natural and human-modified ecosystems is calculated and compared to assess aspects of ecosystem function, such as carbon sequestration therate at that carbon dioxide is photosynthetically removed from the atmosphere. Several systems ecologists now include humans aspartofan expanded ecosystem, the ecological—economic system. Unlike Clements, the new homeostasis entailed a dynamic and open ecosystem that could theoretically allow periodic flows of organisms, materials and energy across its boundaries.

The Odums and subsequent ecosystem ecologists became the foremost proponents of ecosystem-focused science in the s and s, engaging in large-scale research projects in diverse biomessuch as grasslands, deciduous forests, tropical forests, etc. to advance theoretical understanding. From a policy perspective, many ecosystem ecologists advanced the preservation of nature untouched, as far aspossible,bythe human hand. Although systems ecology provides a holistic framework for the consideration of ecosystems,community and population ecology continue to be important approaches to understanding species diversity, distribution and turnover. Proponents of population ecologysuch as Robert MacArthur argued that unified ecosystem theory failed to generate testable hypotheses, producing instead abstractions thatwere notveryuseful for disciplinary advancement.

Aut ecology and synecology play critical roles in the field ofconservation biology, which is concernedwith the conservation of species and other higher levels of biotic diversity. Population ecology autecology focuses on demographic patterns and changes, geographic distribution of species abundances and the processes that influence such patterns. Among such processes are competition, predation, dispersal and extinctions. MacArthur andhis research colleague Edward 0. Wilson conducted studies of species diversity on islands in the Caribbean and the results of their work formed the basis for their theory of island biogeography published in With increasing island size or decreasing distance from the mainland — or both — the rate of species increase drops off after some point, and species richnessreaches an equilibrium.

The theory of island biogeography is explicitly linked to the metapopulation concept in ecology in drawing attention not only to populations in individual patches, but also toward how those patches and their populations are connected in space and time to form a metapopulation. Island biogeography theory has been applied extensively in the field of conservation biology and reserve design wherein reserves may be viewed as islands supporting species richness and has inspired much debate about the relative biodiversity merits of singlelarge or several small SL0SS reserves.

Population ecology examines the geographic range of populations individuals of a species within alocalarea as influenced by that of suitablehabitat, and focuses on population dispersion e. al Within the Amazon Rainforest specifically, deforestation is a huge issue that has many hidden ramifications often overlooked by policymakers. Throughout history evolution has played a large role in the development of society. For the most part, organisms have been locked in toward a certain level of intelligence. Species develop and improve overtime and each species finds their role in the ecosystem.
