2 Friday FRIDAY: 9 / 12 OBJECTIVE #_4-5 TOPIC: Ecology Relationships Daily Grade- Earthworm Activity DW GRADE: 2 1 0

3 OBJECTIVES 4- --COMPARE and give examples of an organism's habitat / niche 5- --GENERALIZE how organisms cooperate and compete with each other for similar resources -EXPLAIN how this affects their growth and reproduction. Add to objectives EVERY night as REVIEW!!

4 2.1 PRINCIPLES of ECOLOGY WHAT YOU WILL LEARN -difference between biotic & abiotic factors -levels of biological organization -difference btwn an organism s habitat & niche

5 MAIN IDEA -biotic & abiotic factors work together in an ecosystem

6 ECOLOGY VOCABULARY: DEFINE: Species -group of organisms that can interbreed and produce fertile offspring

7 -Organisms depend on living & non-living factors in their environment BIOTIC:-living factors in environment -EX: plants, animals, insects, mold, fungus ABIOTIC:-non-living factors in environment -EX: sunlight, water, temperature, soil type, rocks, minerals, wind, ph, salinity THE BIOSPHERE organisms adapt to abiotic factors in their natural environments A change in these factors could cause an unhealthy environment & possibly result in death

8 THE BIOSPHERE -SEQUENCE the abiotic and biotic factors. A A B A B B

9 LEVELS of ORGANIZATION LIST biological levels of org from LARGEST (bottom) to SMALLEST (top) organism population community ecosystem biome biosphere

10 LEVELS of ORGANIZATION IDENTIFY: each level of organization that is described -organism: -an individual living thing made of cells (ex: fish) -population: group of organisms of same species/same place/ same time (ex: school of same species fish) -biological community: -interacting populations of all species in same place at same time (ex: different type fish, marine plants)

11 LEVELS of ORGANIZATION -ecosystem: -all different populations in a community and the abiotic factors that make it function (community & abiotic factors such as water temp, salinity, ph, etc.) -Biome: -large group of organisms that share same climate and have similar types of communities (ex: coral reefs off FL Keys) -Biosphere: -portion of earth that supports life -analogy--the peel of an orange

12 FOLDABLE: levels of organization 1-FOLD top right corner down to make a triangle 2-IDENTIFY & LIST the levels of organization -Smallest at top largest at bottom 3- CUT across the horizontal line. 4-Area NOT CUT : DEFINE the level 5-Area in CUT FLAP: DRAW a picture example Ex: -fish -bunch of same fish -all living things in fish environment -living & non-living environment

13 ECOSYSTEM INTERACTIONS HABITAT: An area where the organism lives NICHE: role an organism has in its environment-how the species meets its specific needs for -SUSTAIN LIFE -food, shelter, water

14 ECOSYSTEM INTERACTIONS MODEL a community with several organisms. Show 2 organisms occupying the same niche. Beside your sketch, explain why those 2 organisms cannot usually occupy the same niche for long. -two organisms cannot occupy the same niche for long -compete for same resources -one species will out compete the other

15 COMMUNITY INTERACTIONS Competition: -2 organisms need the same resource Basic needs food/water/ shelter/etc Strong survive / weak die Predation: - +/- - 1 organism consumes another organism predator/prey

16 COMMUNITY INTERACTIONS SYMBIOSIS- (3 types) -close relationship between 2 organisms Mutualism (+ / +) both species benefit EX: crocidile/plover flies (teeth cleaned/food) Commensalism (+ / 0) one organism is helped while the other is unaffected, neither helped nor harmed EX: remora sucker fish /shark Parasitism (+ / -) one organism benefits, the other is harmed EX: misquito/human, ticks, fleas, intestinal worms

17 COMMUNITY INTERACTIONS ++ (both benefit) +- (1 benefits/1 hurt) +o (1 benefits/1 unaffected) competition predation 2 organisms / SAME resource act of 1 organisms consuming -basic needs[food/shelt/water] another predator prey symbiosis -relationship between 2> different species that live together in direct contact commensalism mutualism parasitism + / O + / + + / -

18 COMMUNITY INTERACTIONS CREATE a journal entry CHOOSE 1 plant or animal IDENITFY 3 relationships

19 COMMUNITY INTERACTIONS MATCH each term with the BEST definition-- D N E A G O H 1-ecology 2-biosphere 3-biotic factor 4-abiotic factor 5-population 6-biological community 7-ecosystem C I K 8-biome 9-habitat 10-niche

20 COMMUNITY INTERACTIONS MATCH each term with the BEST definition-- L J B M F 11-predation 12-symbiosis 13-mutualism 14-commensalism 15-parasitism

21 VOCABULARY A- Nonliving factors in an organisms environment. ABIOTIC FACTOR B- The relationship between two or more organism that live closely together and benefit from each other. MUTUALISM C- Large group of ecosystems that share the same climate and have similar types of communities. BIOME D- Study of organisms and their relationship/interactions with environment. ECOLOGY E- Living factors in an organism s environment. BIOTIC FACTOR

22 VOCABULARY F- A relationship in which one organism benefits at the expense of another organism. PARASITISM G- Individual organisms of a single species that share same geographic are at the same time. POPULATION H- Biological community and all the abiotic factors that affect it. ECOSYSTEM I- Area where an organism lives. HABITAT J- The close relationship that exists when two or more species live together. SYMBIOSIS

23 VOCABULARY K- A role or position that an organism has in its environment. NICHE L- The act of one organism consuming another organism for food. PREDATION M- A relationship when one organism benefits and the other is neither helped or harmed. COMMENSALISM N- Portion of Earth that supports life. BIOSPHERE O- Interacting populations that occupy same geographic area at the same time. BIO COMMUNITY

24 EXIT FILL-IN: level of understanding of today s objective 4- --COMPARE and give examples of an organism's habitat / niche 5- --GENERALIZE how organisms cooperate and compete with each other for similar resources -EXPLAIN how this affects their growth and reproduction.
