Ecology

Colorado

M2A1 Eric Mackey For this assignment, identify the biome in which you live. Using the readings for this module, the Argosy University online library resources, and the Internet, respond to the following: Explain how humans have impacted the biome in which you live. List the types of environmental damage that have been caused and the species that have been impacted. Describe the major pollution issues for your biome, and elaborate on the sources of this pollution. List any species that have become extinct in this biome. Support your statements with appropriate examples and scholarly references. Write your initial response in approximately 300?350 words. Apply APA standards to citation of sources.

Principles of Ecology Organisms and Their Environment What is Ecology? Ecology: the study of interactions that take place between organisms and their environment The Biosphere Biosphere: the part of Earth that supports life The biosphere includes the top portion of Earth?s crust, all the waters that cover Earth?s surface, and the atmosphere that surrounds Earth. The biosphere is made up of different environments that are home to different kinds of organisms. Ecosystem: all the living organisms living in an area and the nonliving features of their environment Biotic factors: living organisms in an ecosystem (ex. bison, grass, birds, insects) Abiotic factors: nonliving features of an ecosystem (ex. water, temperature, sunlight, soil, air) Levels of Organization

Campbell's Biology, 9e (Reece et al.) Chapter 1 Introduction: Themes in the Study of Life This introductory chapter explores the basic themes and concepts of biology, with emphasis on the core theme of evolution. It also introduces students to the thinking of scientists. Questions are therefore general; however, an effort has been made to include some from each skill level. As in the rest of this test bank, questions that feature art or those for which several questions follow upon some data or a scenario are placed together at the end of the chapter. Multiple-Choice Questions 1) A localized group of organisms that belong to the same species is called a A) biosystem. B) community. C) population. D) ecosystem. E) family. Answer: C Topic: Concept 1.1

Chapter 3 Notes Ecosystem Boundaries Biotic and abiotic components of an ecosystem provide the boundaries that separates them from one another Some have a well-defined boundaries: Like a cave Scientist might define a terrestrial ecosystem as the range of a particular species of interest Ecosystems occur in a wide range of sizes Ecosystem Process Each ecosystem interacts with surrounding ecosystems Change in ONE ecosystem can affect the global environment Photosynthesis and Respiration Nearly all of the energy that powers ecosystems comes from the sun Plants, algae and other organisms have the ability to convert the suns solar energy to usable from of energy, these are called producers/autotrophs

Ecosystem Energetics Laws of Thermodynamics 1st ? Energy can neither be created nor destroyed, only transformed from one type to the other All energy in an ecosystem ultimately comes from the sun 2nd ? In any transfer of energy, energy is lost. Energy is constantly being lost to the environment as heat Primary Productivity Primary Productivity is the production of organic compounds from atmospheric or aquatic CO2, principally through the process of photosynthesis Plants use the product of photosynthesis in 2 ways 1. Plant structures such as proteins, cells, tissues (building the plant body) 2. Fuel for Respiration. This powers such processes as growth, transpiration, reproduction, etc. Gross primary productivity (GPP) ? total amount of energy from photosynthesis

Zoe Collins Mrs. G AP Bio Population Ecology Lab Introduction: For any population, a wide range of conditions can influence population size. Some of these conditions include environmental changes such as weather, habitat quality, and food availability. Other conditions involve interactions with competing populations of other species, and predator-prey relationships.
