Midterm Ecology & Environmental Problems

The Ecological Theory is not being probed in this research; it is limited to be an organizing tool. The interview guide that we use tried to include all the systems in the theory (macro, micro, meso, exo, and crhono5), and their probable relations through different issues, which will correspond to one or more systems. However, even the theory would not define the study, it contributes to the design.

By the 1960s the ecosystem concept had become a central ecological idea.3,4 It dovetailed with the rise of systems thinking in other fields, for instance in cybernetics, a new science that studied feedback and control in any kind of system.

Both human and physical factors impact upon ecosystems due to their holistic nature which means that even small changes in the human or physical environment around them can cause an exponential chain of results. However these factors can be both positive and negative to varying degrees.

Recently a group of grade 11 students went out to the Burrum Coast National Park to undertake in observing the relationship between living organisms and their environment, much like ecologists do. Ecologists seek to understand the dynamics of the plants and the world around them. While out on this field trip we studied three ecosystems of the Burrum Coast National Park, the Banksia forest, mangroves and the pioneer zone.

1.) When taking the organism, population, community and ecosystem approaches to study ecology there are levels that lay out the specific details of what each approach is. Ricklefs stated in the textbook all the four approaches to study ecology. For organism approach, the processes look at the way an individual live in an environment and how this individual behaves and adaptation within its surroundings. The population approach concerns over a group of organisms, the number of female and male, the differences within organisms, the similarity that they share, and their genetic makeup within a population. The processes and structures to understand the community deal with understanding of the diversity and different groups of organisms living

Ecology is the study of how organisms interact with each other and their environment. There are many different types of interactions that can take place in which some organisms benefit and some are harmed. One example of an interaction between organisms where both organisms benefit is mutualism. An example of mutualism takes place between a honeybee and a flower. When a bee lands on a flower it positively benefits by eating the nectar. Then, when it lands on another flower, the pollen from the first flower is transferred to the next flower to help the plant reproduce. Alternatively of mutualism is another type of interaction called competition. In this case, both organisms are negatively affected.

Conservation biology, ethnobotany, Integrated Pest Management (IPM), Ecologically Based Invasive Plant Management (EBIPM) and Permaculture. All of these are newer ideas in the still young field of ecology. Ecology definition, as given by Wilson in “Diversity” “is the study of the interactions of organisms with their environment, including the physical environment and the other organisms living in it.” (396) In this general field new ideas gain popularity and support they spawn off into

Cybernetics theory The variety of a system is the total range of its outputs, its total range of behavior. All organic systems in nature are probalistic: they exhibit variety, and an organs flexibility (its adaptability is a function of the amount of variety that it can generate. Evolutionary adaptation is a result of the interaction of this probalistic process with the demands of the environment. This notion influenced a lot Brian

Ecosystems are a place where organisms can interact with their environment and other organisms in the community. So it makes sense just to say ecology is a branch of biology that deals with the relationships of organisms interacting with their environment and other organisms. Ecosystems have many flora and fauna that need to live by the means of energy. We are talking about sun: the sun is the main source of energy because it starts many processes like photosynthesis, the greenhouse effect, and other cycles. One is the carbon, which in a simple way is the movement of carbon through respiration, photosynthesis, fossil fuel emissions, and animal waste products. Following this is the nitrogen, which is taking the nitrogen

2. Based on this week’s required readings, what are the main causes of threats to the biosphere?

Ecology is the division of biology that deals with the relationships and interactions amongst organisms and their environment, (including other organisms). It derives from the Greek word ‘Okologie’, broken down oikos meaning ‘house, place of dwelling or habitation’ and logia which is ‘study of’. Ecology is literally the study of where organisms live (Ecology, n.d.). It is widely believed that having an understanding of ecology can help us to better manage Australian environments. Since settlement, European land management practices have placed our natural environments under considerable pressure resulting in Australia losing nearly 40% of its forests, and a significant amount of the remaining native vegetation being highly disintegrated (Bradshaw, 2012). Resulting in the degradation of habitats. This essay will discuss how better understanding ecology can assist us with current Australian environmental issues.

1.) When taking the organism, population, community and ecosystem approaches to study ecology one needs consider that there are levels that layout the specific details of what each approach is. For organism approach, the processes look at the way an individual live in an environment and how this individual behaves and adaption within its surrounding. The population approach concerns over a group of organisms, the number of female and male, the differences within organisms, the similarity that they share, and their genetic makeup within a whole population. The processes and structures to understand the community deal with understanding of the diversity and different groups of organisms living in the same place. The ecosystem approach looks at the overall chemical reaction which is the transfer of energy and matter to make life possible. The processes occur in the atmosphere, aquatic, and on land.

An ecosystem contains the circle of life, meaning that every organism that is part of that particular environment is a part of a food chain, or a chain of transfer of energy from one organism to another. To enable us to better keep track of what an organism role is in an environment, organisms are put into trophic levels in a way that organizes them based on their role in an ecosystem.

What is ecology? Provide an example of 3 scales at which ecology can be applied? Name one field of study which is associated with ecology?

Ecology is a branch of environment or natural science that has to do with how living things interact with each other in the nature and to be specific in the same environment. Ecology dates back since Aristotle and Hippocrates, it also content some of the observations of Earth science, genetics and biology. Ecologists can apply their skills to the following fields such as forestry, urban renewal, health science, and agriculture as well as climate change. Climate change relates to changes in the world 's temperature, as you know it global warming is an example of climate change, and in addition, the effect of climate related events, for example, heat waves, hurricanes, droughts, rainfalls, earthquakes, and tornadoes. This essay is about ecology and the climate, and the relationship between the two, within the context of sustainability, which is the capacity of the planet to keep up itself despite the natural occurring changes within the Indian Society and the rest of the world.
