Ecologists Study the Interaction of Organisms within Their Environment

3. Environmental Science is interdisciplinary, in that it includes life sciences, natural sciences, and social sciences to study the interactions of living, nonliving and

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.

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.

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.

Ecology is the branch of biology that studies the relationship between organisms and their environment. Ecology is a basic tool of environmental science.

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.

Read "Lab 3: Biodiversity." This lab will allow you to investigate how various organisms alter their environments. Additionally, it will allow you to

Name and describe the roles of the three main trophic categories that make up the biotic structure of every ecosystem. Give examples of organisms from each category.

Dead zones develop due to excess nutrients getting into water causing eutrophication, which means over-enrichment. River runoff deposits these nutrients, which come from upstream, a large amount from agriculture of the Midwest. Nitrogen and phosphorus, the primary excess nutrients, are limiting nutrients to primary producers, such as phytoplankton, that live in the surface oceans. Since those elements are limiting nutrients, an elevated influx of them will cause an explosion of productivity called an

Ecosystems maintain themselves by recycling energy and nutrients obtained from external sources. At the first trophic level of primary producers i.e. plants and algae, use solar energy to produce organic plant material through photosynthesis.

organisms feed? (You will need to do a little research for this ) If you find a good website or paper please

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.

Biogeochemical cycles are important to the sustainability of all life. Chemical elements necessary for the growth and reproduction of all organisms have a limited quantity on earth at any one time, other than the occasional meteor that brings with it new matter. It is therefore important that the recycling of these chemical elements is efficient. Autotrophs are the basis of almost all ecosystems. The rate that autotrophs produce and transfer energy is vital to the capacity of organisms that can inhabit these ecosystems. To understand the rates in which certain species’ leaves decay and release the energy stored within them can demonstrate how quickly the energy becomes available to organisms in higher trophic levels.
