1 Lesson 1 , 2 and 3 Living Things and the Environment Ecology UnitLesson 1 , 2 and 3Living Things and the Environment
2 Do Now Open your books to page 6 and take a picture walk through the chapter to page 10.
3 What do I need to know as I read? What needs are met by an organism’s surroundings?What are the two parts of an organism’s habitat?What are the levels of organization within an ecosystem?
4 Chapter Vocabulary Organism Habitat Biotic Factors Abiotic Factors SpeciesPopulationsCommunityEcosystemIn the back of your packet on the vocabulary page, write the following terms:
5 Vocabulary checkOrganism: any living thingHabitat: an environment that provides the things the organism needs to live, grow, and reproduce.Biotic Factors: the living parts of a habitatAbiotic Factors: the non-living parts of an organism’s habitat – water, sunlight, oxygen, temperature, soilSpecies: a group of organisms that are physically similar and can mate with each other to produce offspringPopulation: All the members of a one species in a particular areaCommunity: all the different populations that live togetherEcosystem: the community of organisms that live in a particular area, along with their non-living surroundings
6 How are ecosystems organized? 1. Organism – one prairie dog2. Population of Prairie dogs3. Community of different organisms4. Ecosystem- all living and nonliving things interacting on the prarie
7 Hierarchy of Ecosystems In the diagram, where would you place…Organisms? Populations? Community? Ecosystems?Organization of an ecosystem.
9 Do NowUsing pages 6-10, complete the workbook pages numbers 1-18You may work in pairs if you choose to.
10 DO NOW Get a book from the side. Take your ecology packets out and open to last nights homework.
11 Let’s check our answers for 1-18! organismHabitatNeeds food, water, and shelterFalsea, b, dBiotic factorsAbiotic factorsWater, sunlight, oxygen, temperature, soila, cPhotosynthesisb, dA species is a group of organisms that can mate and reproduce offspring.
12 More answers! 13. A, b, c 14. False 15. Community 16. D 17. True 18. An ecosystem also includes abiotic factors
13 Do Now Find pg. 51 in your packet. Use the picture on page 11 to help you answer questions 1-3Use your vocabulary page in the packet to help you answer #4-8
14 Answers to Page 51 1. organism – population – community – ecosystem 2. a.) Buffalo, grass, hawks, snakes, owls, fliesb.) water, soil, sunlight, oxygen, temperaturec.) Trees- hawks underground – wormsprairie – buffalo water – fishEcology is the study of how organisms interact with their environment.
15 Lets Analyze an Ecosystem – pg 52 in packet Biotic factors found in this picture: blue-jay, bear, dragon fly, frog, lizard, fish, squirrel, cattail plant, ferns, grass, treesAbiotic factors found in this picture: warm temperatures, oxygen in the air, soil and rocks, sunlight, waterHabitats (homes of the animals)Bear – forestblue jay – trees, ground, skysquirrel – trees, groundFish – waterLizard – ground, under rocksDragonfly – weeds, sky, near waterFrog – pond, stream, lake
16 Studying Populations Do Now In the back of your packet on the vocabulary page, write the following new vocabulary wordsBirth RateDeath RateImmigrationEmigrationPopulation DensityLimiting FactorsCarrying Capacity
17 Reading the chapter First, open your books to page 13. Then, lets discuss your new vocabulary words.Now, help me with a little demonstration…Have 1 person in the first square, 2 in the second and 4 in the third. Have them pick up a hanful of paperclips (food). Show how more individuals in a fixed area makes it hard to move and compete for food
18 Do NowGet a Science book from the side. Using pages 13-19, define the vocabulary words you wrote yesterday.rabbit
19 Vocabulary Check1. Birth Rate: the number of births in a population in a certain amount of time2. Death Rate: the number of deaths in a population in a certain amount of time.3. Immigration: moving into a population4. Emigration: leaving a population5. Population Density: the number of individuals in a specific area – population density = number of individuals / unit area6. Limiting Factors: an environmental factor that causes a population to decrease ( things like food, water, weather and space are limiting factors)7. Carrying Capacity: the largest population an area can support.
20 Use the equation to see how many frogs are in 1 sq. meter Use the equation to see how many frogs are in 1 sq. meter Population density = # of individuals Unit Area5 metersCount the X’s = divide 20 by 5005 meters
21 How to solve the problem Count the number of x’sDivide that number by the unit area which is 25 meters. ( 5x5)Your answer should be 1 frog per sq meter.X= 25 frogsUse board to show math
22 Do Now Open packet to p. 58Fill in the missing information in your guided notes packet.Hand out homework sheet as study guide (living things---two sides)
23 Do NowPlease get a science book and then get your homework out (worksheet pg. 58 in packet)
24 Page 58 Answers Take out your packet and open to page 58 Populations can change in size when new members are added or when members leave the population.6. Through the birth of offspring7. Birth Rate8. Dying9. Death Rate10. False11. B – moving into a population12. A - Leaving a population13. TrueLimiting factorsfood, water, space and weather are the limiting factors.Carrying capacityTrueFrost can kill organisms, floods and hurricanes can wash away nests and burrows
25 Answers to Study Guide Any living thing Environment Habitat Living – nonlivingAlive (has the 7 characteristics of life)Any living organismAbiotic FactorsSunWaterOxygenTemperatureSoilLevels of organizationSpeciesPopulationCommunityecosystem
26 Answers to Study Guide 1a. Food, water, shelter LEVELS OF ORGANIZATION organism, population, community, ecosystem1a. Food, water, shelter1b. It would either leave or die2a. Biotic factors are the living things in an ecosystem and abiotic factors of the non living things in an ecosystem2b. sunlight, water oxygen, temperature and soil (SWOTS)2c. Without sunlight, there would be no plant life and we need plants not only for food but also for oxygen. Without water, no living organism could survive. It is essential for life.3a. Organism, population, community, ecosystem3b. A community because a community means all the different populations in an area living in the same ecosystem.3c. If one population decreases, another might also because they depend on one another for food. For example, if the numbers of mice were low, then the hawks and owls would have a hard time finding food and their numbers could be in trouble too.
