Organism, Community And Ecosystem Approaches To Study Ecology

Ecology is how organisms interact with each other and the environment. The Lion King is linked to ecology by showing how organisms interact with each other and the environment. My three topics are how symbiotic relationships are important to a community, how limiting factors affect a community, how communities respond to abiotic or biotic factors, and how this is linked to the movie and Ecology. Symbiotic Relationships are interactions between two species and how they affect each other. There are three different types of symbiotic relationships Mutualism, Commensalism, and Parasitism.

The Ecological Systems Theory was founded by Urie Bronfenbrenner. This theory focuses on the impact of the environment on a child’s overall development. The identifying characteristics of Bronfenbrenner’s theory are the five systems used to organize external influences within a child’s development. These systems are the microsystem, mesosystem, exosystem, macrosystem, and chronosystem. Each system is aligned with specific interaction levels. The microsystem is considered to be the most intimate of the levels, in which development is dependent on the immediate environment. The immediate environment would include adults, peers, and siblings with influence to learning new behaviors and the environment in which the

As defined by “Environmental Science- 14th Edition”, an ecosystem is “a set of organisms within a defined area or volume that interact with one another and with their environment of nonliving matter and energy.” I will be using the computer simulation to alter the interactions of the organisms in the ecosystem to see what changes occur.

Urie Bronfenbrenner’s ecological systems theory encompasses every aspect of Adam Lanza’s development. His theory separates the environment into four distinct systems, which are Microsystem, Mesosystem, Exosystem, Macrosystem and Chronosystem. In the following, I will apply his theory to the specific case as described above. I will also analyze

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.

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.

Aquatic environments require different methods for adaptation. The pressure in water increases as depth increases and aquatic organisms have to deal with it. Mobility of small animals versus larger ones help the ones with greater SA:V flow or be moved by currents, which is a disadvantage for bigger animals that have to constantly move. Light limitations also affect living things in water, mostly plants because they have to photosynthesize to grow, and the attenuation of light increases in depth, they have to take advantage of other resources to get the light they need and the nutrients to survive. Salt tolerance is vital; the process of osmosis moves water from high concentration of solutes to low concentration of solutes, if an organism doesn’t have enough salt contents starts losing water and dehydrates

31. Question : Which of the following is best defined as a community of plants, animals, and microorgaisms that are linked by energy and nutrient flows and that interact with each other and with physical environment

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.

A population consists of all individuals of a species that occur together at a given place and time. All populations living together and the physical factors with which they interact compose an ecosystem.

In the ecosystem organisms rely on each other for food and protection. The Food chain is like a pyramid you have the producers, primary consumers, secondary consumers, tertiary consumers, and quaternary consumers. It’s an almost perfect balance and if any level were to just stop existing then the food chain would be destroyed. An example of organisms relying on others is an issue of isle royale were the wolves and moose population are in jeopardy. This relationship is important because without the other animal the population would die.

Food Pyramids are pyramid graphs showing the different levels of population, food energy, and other factors. Some of these pyramids include the Pyramid of Biomass which shows the total amount of dry mass per trophic level. The trophic level of an organism is the position it occupies in a food chain. The other pyramids are Pyramid of Numbers, which show how many of the creature per trophic level and Pyramid of Energy which shows how much total energy is available at each trophic level. This pyramid cannot be inverted because energy always decreases the higher up you go.

This chapter reviews concepts and terms you learned in your introductory ecology or environmental science course.

Ecology today can be defined as “the study of the interrelationships between living things and their environment”. It is important to understand that when we say that ecology includes the “environment”, we are talking about everything that is external to an organism, all the biotic and abiotic. Nowadays it also attempts to understand and explain the how and why of the origins and mechanisms of interactions.
