Organization of Life Ecology K. Stacker SEV2. Students will demonstrate an understanding that the Earth is one interconnected system Element a: Describe how the abiotic components (water, air, and energy) affect the biosphere. Element b: Recognize and give examples of the hierarchy of the biological entities of the biosphere (organisms, populations, communities, ecosystems, and biosphere). Essential Question: Why can’t an organism survive in total isolation?
The Game of Life Water Food Shelter L I F E The object of the game is to fill in the spaces under each category with words or phrases related to the topic of LIFE. The first space under each category has to be filled in with a word or phrase that starts with the letter ‘L’. The second space under each category must start with the letter ‘I’ and so on. There are no right or wrong answers in this game. If you can explain how a word or phrase relates to life and to the category you get credit for it. Water Food Shelter L I F E 10 points for words or phrases no one has thought of. 5 points for words or phrases someone else has thought of. 0 points for blank spaces.

Why & How are living things interrelated? What is Ecology? Ecology is the scientific study of the interactions among organisms and their environment. Why & How are living things interrelated? All living things are interrelated because we need the same basic elements: food, water, and shelter. We are all dependent upon one another for these needs. What is the definition Of Biosphere, Abiotic, Biotic, and Ecosystem?
What are the 2 Types of Ecosystems? of Aquatic Ecosystems?
What are the Characteristics of an Ecosystem?
What determines the type of ECOSYTEM that will develop? Two of the most important things that determine the type of ecosystem that will develop in a given part of the world are temperature and precipitation (rainfall).
What affects the kinds of ORGANISMS that will live in a particular ECOSYSTEM? Many other things affect what kinds of organisms will be part of the different ecosystems, such as: seasonal fires, type of soil, types of plants, wind, closeness to the sea…
What is The Organization of Life? Each level of the pyramid is linked to those above it. How do you know if something is living? All organisms: Are made up of cells Grow/develop Adapt/change/evolve Reproduce Doe For each level, provide a definition and an example Deer Deer, Elk, Wolves, Trees, Bears, Mice, Etc. Plants/Animals + Habitats All Ecosystems are Part of the Biosphere
Putting it all Together: The Organization of Life All organisms: Made up of Cells Grow/develop Adapt/change/evolve Reproduce Each level of the pyramid is linked to those above it.
What is a Habitat? Niche? What is a habitat? Where an organism lives Shared by many species Organism develop strategies to live and reproduce in their habitats Can change or disappear rapidly What is a niche? Role a species has in its environment. “Job” Organisms have unique strategies and structures which reduce competition with other species in the habitat Advantageous to occupy a niche that is very different from other species in the environment - no two animals can occupy the same niche Change is gradual (evolution)
What is Symbiosis? Symbiosis is a close, long-term relationship or association between two or more species (species interactions). What are the types of symbiotic relationships? Types of symbiosis Definition Helpful? Harmful? Neutral? Example Parasitism A relationship in which one organism benefits at the expense of another (by living off the other) X Dogs & ticks Tapeworms & humans Commensalism A relationship in which one organism benefits and no harm comes to the other Clownfish & Sea Anemone Barnacles & Whales Mutualism A relationship in which both organisms benefit Lichen (Moss and Algae) E. Coli & Humans
