 Summarize the characteristics of the levels of organization within ecosystems (including populations, communities, habitats, niches, and biomes).  Objective: summarize the characteristics of each level of organization w/in ecosystem  By the end of the lesson, 80% of SWBAT summarize the char of each level of organization w/in ecosystem.  Formative: Question checks, choral responses, indiv q/a, pairs quiz  Summative: graded test next Monday. See A-5  Bell Ringer : previous slide(s)  Guided Practice: use scaffolding notes from support document LEARN AND SING SONG.  Closure: questioning(thumbs up/down—(f))/stand and deliver (m) Independent q/a and quiz (tomorrow), rapid fire

Homework for tonight  Habitat  Role  Vegetation  Climate  Adaptations  Make sure you have the definition and a picture.

1. Did you know…  that the levels of organization of the living world include the individual organism, populations, communities, ecosystems, and biomes. Each level is defined by the type and number of organisms or the abiotic factors present. biomes ecosystems communities Individual organisms populations Ecology 3/25/15

2. Levels of Organization  A. Populations : Ex is all dogs of same species in 1 place at 1 time.  All of the individuals of a given species in a specific area or region at a certain time.  Members of a population compete for food, water, space, and mates ; for example all of the dogs in my yard.

B. Communities  All the different populations in a specific area or region at a certain time.  For example, all of the crabs, seagulls, and sea grass at the beach are part of the same community.  Communities involve many types of interactions among populations. DESCRIBE SOME: ________________________(at least 3)__  Some of these interactions involve the obtaining and use of food, space, or other environmental resources.

C. Ecosystems and One or more communities in an area and the abiotic factors, including water, sunlight, oxygen, temperature, and soil.

4.Why are highly diverse communities more stable? A.A low diversity ecosystem does not provide substitutes for food supply. B.A low diversity ecosystem provides too many organisms for a food supply. C.A high diversity ecosystem does not provide substitutes for a food supply. D.A high diversity ecosystem is not possible in normal communities.  Buzzards play an important role in the environment by eating the carcasses of dead animals. This role, that the buzzard plays, is called its —  A.habitat. B.niche. C.biome. D.ecosystem

2. Levels of organization a. Within an ecosystem, organisms have specific places where their needs are met and specific roles within the ecosystem. b. The place where an organism lives in order to obtain its food, water, c. shelter and d. other things e. needed for f. survival is called g. its habitat.

 3. The particular role of an organism in its environment including type of food it eats, how it obtains its food and how it interacts with the other organisms is called its niche. For example, the niche of a bee is to pollinate flowers as it gathers nectar for its food.

the levels of ecology: ( To the tune of the 12 days of Christmas )  One the first day of ecology my dear teacher ‘splained to me that populations are organisms just alike in 1 place at 1 time  On the second day of ecology, my dear teacher ‘splained to me that communities are all the populations in 1 place at 1 time   On the third day of ecology, my dear teacher ‘splained to me that ecosystems include abiotic factors like water, sunlight, soil oxygen, and temperature, along with all the communities in 1 place at 1 time.  On the fourth day of ecology, my dear teacher ‘splained to me that biomes include all the ecosystems grouped BY climate, you know the weather, and ALL the green leafy stuff in 1 place at 1 time.  On the fifth day of ecology my dear teacher ‘splained to me that biomes are made of ecosystems, THE living and nonliving in one place at one time. The communities are all the populations in one place at one time, populations are identical organisms in one place at one time.

Biomes  Individual ecosystems grouped together according to the climate and the predominant vegetation and characterized by adaptations of organisms to that particular environment
