Section 2.2 Flow of Energy in an Ecosystem Autotrophs capture energy, making it available or all members of a food web. Autotrophs Heterotrophs: herbivore, carnivore, omnivore, detritivore.
MODELS OF ENERGY FLOW TROPHIC LEVEL- Food chains- producer→heterotroph→consumer Food webs-producer→ 1 st consumer →2 nd consumer →3 rd consumer
Ecological Pyramids BIOMASS-- PYRAMID OF ENERGY-10% RULE PYRAMID OF BIOMASS- PYRAMID OF NUMBERS-
CYCLING OF MATTER CYCLES IN THE BIOSPHERE Matter- Nutrient- Biogeochemical cycle- Explain why it is important to living organisms the nutrients cycle.
WATER CYCLE USE FIGURE 2.17 TO TRACE PROCESSES THAT CYCLE WATER. Identify three processes in the water cycle. What is a hydrologists?
THE CARBON AND OXYGEN CYCLE How does carbon move from the abiotic to the biotic parts of the ecosystem?
THE NITROGEN CYCLE NITROGEN FIXATION- ELECTRICAL STORMS- PLANTS ABSORBS FROM SOIL- DENITRIFICATION-
THE PHOSPHOROUS CYCLE Phosphorus essential element for the growth and development of organisms. Two cycles-one is short term- and long term Found in small amounts in soil May limits the growth of producers. Who are the producers.
Construct a simple food web Food web must have at least 5 organisms listed. Page 55-complete the document-based questions; numbers 40 and 41
