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 MAIN IDEA -biotic & abiotic factors work together in an ecosystem ADD under MAIN IDEA DEFINE: species: -group organisms -reproduce THE BIOSPHERE -Organisms depend on living & non-living factors in their environment BIOTIC: -anything that is / or was alive in the environment -EX: plants, animals, insects, mold, fungus ABIOTIC: -non-living factors in environment -EX: sunlight, water, temperature, soil type, rocks, minerals, wind, pH, salinity -organisms adapt to abiotic factors in their natural environments -A change in these factors could cause an unhealthy environment & possibly result in death THE BIOSPHERE -SEQUENCE the abiotic and biotic factors. A A A B B B LEVELS of ORGANIZATION LIST biological levels of org from LARGEST (bottom) to SMALLEST (top) organism population community ecosystem biome biosphere 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) LEVELS of ORGANIZATION -ecosystem: -all different populations in a community and the abiotic factors that make it function (community & abiotic factors) -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 -“ball of life” -analogy--the peel of an orange 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 [sustaining life] -SUSTAIN LIFE -food, shelter, water ECOSYSTEM INTERACTIONS MODEL a community with several organisms. Show 2 organisms occupying the same niche. 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 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 COMMUNITY INTERACTIONS ++ (both benefit) +- (1 benefits/1 hurt) competition +o (1 benefits/1 unaffected) predation 2 organisms / SAME resource -basic needs[food/shelt/water] symbiosis act of 1 organisms consuming another predatorprey -relationship between 2> different species that live together in direct contact commensalism +/O mutualism +/+ parasitism +/- COMMUNITY INTERACTIONS Mutualism (+ / +) • both species benefit EX: crocidile/plover flies (teeth cleaned/food) Commensalism (+ / O) • 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 COMMUNITY INTERACTIONS CREATE a journal entry CHOOSE 1 plant or animal IDENITFY 3 relationships VOCABULARY MATCH each term with the BEST definition-D ____1-ecology N ____2-biosphere E ____3-biotic factor A ____4-abiotic factor G ____5-population O ____6-biological community H ____7-ecosystem C ____8-biome ____9-habitat I K ____10-niche VOCABULARY MATCH each term with the BEST definition-L ____11-predation J ____12-symbiosis B ____13-mutualism M ____14-commensalism F ____15-parasitism 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 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 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 HONORS: GOING FURTHER SUMMARIZE: Bacteria live inside our bodies. Analyze helpful, neutral, and harmful things that bacteria do while living in our bodies. Incorporate the terms parasitism, mutualism, habitat, and niche in your discussion. -helpful bacteria use our body as their HABITAT, they occupy the NICHE and keep harmful bacteria out. -The helpful bacteria can help us by eating harmful substances: MUTALISTIC -Harmful bacteria can act as PARASITES by eating food we need, causing infections.
