5-1-2012 Warm-up On the gold paper “The Biosphere” fill in the first block…3.1 How do we study life? Under “What I know”. In the SAME block, write what you think ECOLOGY is. *EVERYONE get s folder and put your name on it.
Today • What is Ecology? Discussion • What factors effect an environment? -worksheet/discussion HW: yes…we will discuss at the end
What is Ecology? • Ecology is the study of interactions among organisms and between organisms and their environment. ECO= means house (economics-human interactions based on money and trade, in nature= an organisms’ “house” and energy and nutrients needed to survive
Life on a Global Scale= BIOSPHERE • Biosphere contains the combined portions of the planet in which life exists, including land, water, and air or atmosphere. • Put the “Levels of organization” in order
Species • group of organisms so similar to one another that they can breed.
Population • groups of individuals that belong to the same species and live in the same area.
Communities • assemblages of the different populations that live together in a defined area.
Ecosystem • a collection of all the organisms that live together in a particular place as well as their nonliving or physical environment.
Biome • A group of ecosystems that have the same climate and similar dominant communities.

Consider the ENVIRONMENT:-conditions or factors surrounding an organism * some factors are living… *some factors are non-living… Biotic Abiotic
Biotic Factor: • Living components of an ecosystem • Living organisms that effect other living organisms • Ex: bacteria, fungi, plants, animals…
Abiotic Factor: *Non-living items that effect living organisms and their environment Ex: Temperature, sunlight, rocks, soil, climate, topography…..
Biotic? Abiotic?
Summary:How do we study life? • Field of ecology • Organisms & their environment (biotic/abiotic) • Eco=house • Levels of organization: species population community Ecosystem biomeBiosphere
Activities: • Biotic and Abiotic factors worksheet HW: • Choose an “Environment” to assess in your Lab book: -title: Biotic and Abiotic Factors in an Environment -Sketch an environment or cut/paste a picture -List all Biotic and abiotic factors.
