PRINCIPLES OF ECOLOGY ORGANISMS AND THEIR RELATIONSHIPS OBJECTIVES
PRINCIPLES OF ECOLOGY ORGANISMS AND THEIR RELATIONSHIPS
OBJECTIVES o EXPLAIN THE DIFFFERENCE BETWEEN ABIOTIC FACTORS AND BIOTIC FACTORS o DESCRIBE LEVELS OF BIOLOGICAL ORGANIZATION o DIFFERENTIATE BETWEEN AN ORGANISM’S HABITAT AND NICHE
August 29, 2011 BELL RINGER o What are the steps in the Scientific Method.
August 30, 2011 o Define the term organism o Define the term niche o Define the term biosphere
Milestones in Ecology o Ecologyo Timeline on page 32 -33 - conservation of Yellowstone to Wangari Maathai. o Biosphereo Biotic Factorso Abiotic Factorso Compare and contrast abiotic and biotic factors
LEVELS OF ORGANIZATION o Organism o Population o Biological community o Ecosystem o Biome o Biosphere o Refer to figure 2. 6 as you read.
ECOSYSTEM INTERACTIONS o Interactions between an organism and its ecosystem. o Habitat o Niche o Compare and contrast a habitat and a niche.
COMMUNITY INTERACTIONS o COMPETITION o PREDATION o SYMBIOTIC RELATIONSHIPS: o Symbiosis o Mutualism o Commensalism o Parasitism
Section 2. 2 Flow of Energy in an Ecosystem o Autotrophs capture energy, making it available or all members of a food web. o Autotrophs o Heterotrophs: herbivore, carnivore, omnivore, detritivore.
MODELS OF ENERGY FLOW o TROPHIC LEVELo Food chains- producer→heterotroph→consumer o Food webs-producer→ 1 st consumer → 2 nd consumer → 3 rd consumer
Ecological Pyramids BIOMASS-PYRAMID OF ENERGY-10% RULE PYRAMID OF BIOMASSPYRAMID OF NUMBERS-
CYCLING OF MATTER o CYCLES IN THE BIOSPHERE o Mattero Nutriento Biogeochemical cycleo Explain why it is important to living organisms the nutrients cycle.
WATER CYCLE o USE FIGURE 2. 17 TO TRACE PROCESSES THAT CYCLE WATER. o Identify three processes in the water cycle. o What is a hydrologists?
THE CARBON AND OXYGEN CYCLE o How does carbon move from the abiotic to the biotic parts of the ecosystem?
THE NITROGEN CYCLE o NITROGEN FIXATIONo ELECTRICAL STORMSo PLANTS ABSORBS FROM SOILo DENITRIFICATION-
THE PHOSPHOROUS CYCLE o Phosphorus essential element for the growth and development of organisms. o Two cycles-one is short term- and long term o Found in small amounts in soil o May limits the growth of producers. o Who are the producers.
Construct a simple food web o Food web must have at least 5 organisms listed. o Page 55 -complete the document-based questions; numbers 40 and 41
