Human Exercises : Natural State Of The Type Specific Aquatic Habitat

Ecological theory describes four levels of the environment that interconnect and impact people. Moving from the most intimate individual system to a broader inclusion you can identify the many systems that play a role in individual’s lives and well-being. These interactions could be harmonious and create homeostasis or could be disharmonious and cause stress.

An ecosystem is a community of interacting organisms and their environment. If one of the organisms is disturbed, it can change the trophic cascade which is a sequence of impacts down the food chain. Hannibal supports this statement by writing “keeping these connections going ensures healthy, functioning ecosystems, which in turn support human life.”(578) An example of this is if all of the beavers died the other organisms would go somewhere else or die due because they no longer will have dams to support their ideal habitat.

Ecosystem management takes an integrated view of terrestrial and aquatic ecosystems, integrates ecological concepts at a variety of spatial scales, incorporates the perspectives of landscape ecology so that the range of possible landscapes in an ecosystem is recognized and preserved, and is an evolving paradigm incorporating the objective of ecological sustainability.

Ecosystem: a system formed by the interaction of a community of organisms with their environment

-Ecosystem: any environment containing living organisms interacting with each other and with the non-living parts of that environment.

Ecology is the branch of biology that studies the interactions of organisms with each other, and with their physical and chemical environments. Another main topic discussed in this chapter is ecosystems. Ecosystems are habitats or areas that consists of two basic components. Ecosystems include such things as biotic and abiotic components. Biotic components are living organisms within an ecosystem and abiotic components are things like sunlight, temperature, and rainfall. Within an ecosystem are producer and autotrophs. Producers and autotrophs consist of plants, algae, and bacteria. These two organisms obtain food from inorganic materials and light energy. As to where consumer and heterotrophs obtain energy by eating plants or the animals that eat the plants. An ecosystem is made up of several different parts. Each part of an ecosystem is different from the other. None of these parts within the ecosystem rely on the other. They are all interdependent being either predators or

By definition, an ecosystem is a “community of organisms in an area and the physical factors with which those organisms interact.” Although the key characteristics of an ecosystem are the presence of biotic and abiotic factors, it is the interactions that enables vivacious life to flourish. Whether it is the isopods hidden in the nook under a log or its crustaceous ancestors in the vast ocean, ecosystems are thriving with behavior as its driving force. Effective communication can be observed in countless organisms, which is a testimony to its importance.

In order for an ecosystem to stay an ecosystem there are three aspects that interact with each other:

Furthermore, I prefer to consider Bronfenbrenner’s ecological systems theory (as cited in Santrock, 2007) in order to gain an understanding of an individual’s

The construction of these networks, however, is continuous and brings with it numerous destructive implications for fauna in the area. Multiple features of an ecosystem such as vegetation, dwellings and resources may be affected with the disruption and modification of the natural setting.

The first of these eight points relates to the intrinsic value of nature as seen by deep ecologists. Intrinsic value believes that nature has value in itself and its value is not calculated by what it can offer humans. Naess explains intrinsic value in more depth by stating that “The presence of inherent value in a natural object is independent of any awareness, interest, or appreciation of it by any conscious being.” (Naess, 189) Naess and deep ecologists therefore conclude that giving intrinsic value to all things is important simply because it is a living being and focuses on its value in and of itself compared to its material value. Intrinsic value is important to the deep ecology movement because it gives way to the reasons behind conservation

Environmental, or ecological anthropology looks at the relationship between culture and ecology. Conservation is the protective act of preserving or restoring an environment. It involves saving all populations, species, communities, and ecosystems from uses that are inappropriate (Mulder, Coppolillo 25). Human activities are the major threat to biodiversity, yet human activities can also be the answer to conservation issues.

“Ecological resilience was defined as the amount of disturbance that an ecosystem could withstand without changing self-organized processes and structures” (Gunderson, 2000). Ecological resilience describes the threshold of the stable system. The disturbance into the system is resulting positive and negative feedback which influence the weight and period of the resilience (Gunderson, 2000). Human makes the biggest disturbance into the ecosystem resilience. The argument is whether ecosystem could return into the previous state before shift into new state after introduce by human’s disturbance (Standish et al., 2014)

The ecological approach refers to the study of relationships between groups of people within society and their physical and social environments. The systems approach recognises that people are social beings and that they influence and are influenced by others around them; including individuals, communities and organisations. Urie Bronfenbrenner was a psychologist who developed the bio-ecological systems theory of development. This theory states that you cannot fully understand, or improve the situation of the child or young person without taking into account the context of their lives. This theory also states that there are a variety of different factors that affect the overall health and wellbeing of the child. The Ecological Model includes a range of different systems including the; Biological level, Microsystem, Mesosytem, Exosystems, Macrosystem and Chronosystem.

Ecology is the study of the distribution and abundance of organisms, their interactions between each other and their environment, and the structure and function of ecosystems. To this end, the scale (spatial, functional, temporal, organizational, etc.) at which we observe nature and the multitude of environments that comprise it is an extremely important factor in the study of ecology. Dumping sewage effluent in the middle of a small pond is not going to register even a slight disturbance on a global or even regional scale , but there is a still massive disturbance to the organisms at the small scale of that pond ecosystem. Similarly,
