Ecology
Ecology is a biology branch which focuses on examining living organisms in their environment. Ecologist study the inactions of organisms within their environment, including ecosystems, communities and populations that influence life on earth. Economist can see the interconnection of animal and plant populations shape physical environments and the interactions of the different species.(N/A, 2014)
The biota of earths process of biochemical's is four spheres which consist of atmosphere, hydrosphere, biosphere and lithosphere. These are driven by solar energy, decomposers, producers and the consumers that move materials in quantity. This cause inputs and outputs of inorganic and organic nutrients The

consumers eat the producers using some chemicals in their body, 3. consumers and producers make waste returning chemicals back to the environment and 4. decomposers break down organic complex molecules dead organisms, waste and litter from plants. Rocks that are weathering and erosion gives to the abotic reservoir. Inorganic molecules from the reservoir are used as new material to make organic molecules by the producer and this cycling is global. (Simon, Dickey, Reece and Campbell, 2012,P440)
Community structure are species interacting within the communities and create food chains. Evolution brings change in relationships as species adapt to one another through the coevolution process. The elements of an biotic community is the pyramid structure which is made up of levels. The food chain passes food energy from one level to another and this energy is chemical or photosynthesis. The pyramid base has the producers and take this energy to produce organic organisms from the inorganic ones. The consumers depend on these producers indirectly or directly. The base pyramid level is different from one community to another. A terrestrial community plants that are multicellular make the base, where as lakes that are freshwater it takes a combination of algae that is single celled and plants that are multicellular. Freshwater streams does not have living plants but detritus for an energy base and plankton builds the oceans.
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.
Unit One Aha Thesis - Ecosystems Ecosystems are filled with abiotic and biotic factors. They both need the other for survival. Energy and nutrients flow through the trophic levels which helps ecosystems change and survive. Abiotic and Biotic Factors Abiotic and biotic factors are connected in many ways. One connection in Planet Earth was an antelope jumping into the water to be safe from the hunting dogs.
Ecosystem: a system formed by the interaction of a community of organisms with their environment
Read "Lab 3: Biodiversity." This lab will allow you to investigate how various organisms alter their environments. Additionally, it will allow you to
3. Environmental Science is interdisciplinary, in that it includes life sciences, natural sciences, and social sciences to study the interactions of living, nonliving and
Varun Tandon AP Biology Homework 1. Ecology is the study of organisms and how they interact with the environment. The major subfields of ecology are organismal ecology, population ecology, community ecology, ecosystem ecology, landscape ecology, and biosphere ecology. Organismal ecology deals with how a specific organism interacts with and deals with challenges in an environment. Population biology deals with how the environment and other factors affect individuals of a population.
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.
Decomposers process a large amount of organic material and return nutrients to the ecosystem in inorganic form, which are then taken up again by primary producers. Energy is not recycled during decomposition, but rather is released, mostly in heat. (Annenberg Learner, n.d)
organisms feed? (You will need to do a little research for this ) If you find a good website or paper please
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.
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
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.
Ecology is the tool used to better understand the causes, effects, and potential mitigation of environmental problems.
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.
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.
