Ecologists Study the Interaction of Organisms within Their Environment

“Rabbits and Wolves” Introduction I will be conducting a computer simulation called “Rabbits and Wolves”. In this experiment I will be interaction with a simple forest ecosystem model that will simply take into account three organisms: rabbits, wolves, and grass. As defined by “Environmental Science- 14th Edition”, an ecosystem is “a set of

An ecosystem is the dynamic complex of plant, animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are systems through which incoming solar energy is captured and channelled through a hierarchy of life forms. Each ecosystem has its own characteristic plant and animal community.

Not many people understand the seriousness of endangered species. Some sources go as far as trying to prove that the act does more harm than good. They do not realize how drastically their lives can be changed if one part of the food chain is taken away. In the essay

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.

Carefully review the Grading Rubric before beginning the assignment. Read "Lab 3: Biodiversity." This lab will allow you to investigate how various organisms alter their environments. Additionally, it will allow you to

3. 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

*The nitrogen cycle converts atmospheric nitrogen into a usable form for plants and animals, and then reconverts it to

In this lab write up, the population growth of a variety of living organisms was analyzed and upon analysis of graphs and background information given within the laboratory course notebook, the conclusion was made that abiotic factors are related to biotic factors in an ecosystem, if one factor is varied

The biosphere is the earth, the higher power that houses every living thing and non living thing, ecosystems, communities, populations and organisms. Then the organ systems and organs, tissues, cells, organelles and molecules, atoms all make the organism. This goes back to one of the seven properties of life known as order that is showing the organization and the different stages which make up the biosphere. Ecosystems are a place where all living and nonliving things exist. For example in the rainforest there are water, trees, animals and everything needed for all living things to survive. Living things need to interact with nonliving things such as animals drinking water in order to keep them hydrated and healthy. Within an ecosystem, there are communities. Within an ecosystem, you will not see a fish living in a tree. They would be in their community, the ocean, along with whales, seaweed, plants and jellyfish. Within the community, there are different types of species such a group of whales that are one species or a group of jellyfish another species. One cannot class a whale with a jellyfish. Although they live in the same communities they carry different DNA and are from different populations that also goes back to reproduction; organisms can only reproduce their kind. Then there are organisms meaning one specific living thing such as a jellyfish or a human. Organisms are

a) 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.

Introduction 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.
