Energy Flow in an Ecosystem copyright cmassengale
copyright cmassengale Energy Flow Energy in an ecosystem originally comes from the sun Energy flows through Ecosystems from producers to consumers Producers (make food) Consumers (use food by eating producers or other consumers) copyright cmassengale
copyright cmassengale Producers Sunlight is the main source of energy for most life on earth. Producers contain chlorophyll & can use energy directly from the sun copyright cmassengale
copyright cmassengale Autotrophs An Autotroph is any organism that can produce its own food supply! Autotrophs are also called Producers Plants, algae, some protists, & some bacteria are examples copyright cmassengale
copyright cmassengale Niche of a Producer Captures energy and transforms it into organic, stored energy for the use of living organisms. May be photoautotrophs using light energy (e.g. plants) May be chemoautotrophs using chemical energy (e.g. cyanobacteria) copyright cmassengale
copyright cmassengale Photoautotroph Producer That Captures Energy from the sun by: Photosynthesis Adds Oxygen to the atmosphere Removes Carbon Dioxide from the Atmosphere Algae copyright cmassengale
Habitat of Photoautotrophs On Land Plants In The Sea Algae Tidal Flats & Salt Marshes Cyanobacteria copyright cmassengale
Called a Black smoker (thermal vent) Chemoautotrophs Capture energy from the bonds of inorganic molecules such as Hydrogen Sulfide Process is called Chemosynthesis Often occurs in deep sea vents or gut of animals Called a Black smoker (thermal vent) copyright cmassengale
Tube Worms living in Black Smoker copyright cmassengale
Heterotrophs eat other organisms to obtain energy. (e.g. animals) Consumers Heterotrophs eat other organisms to obtain energy. (e.g. animals) Herbivores Eat Only Plants Carnivores Eat Only Other Animals copyright cmassengale
Heterotrophs eat other organisms to obtain energy. Consumers Heterotrophs eat other organisms to obtain energy. Omnivores (Humans) Eat Plants & Animals Detritivores (Scavengers) Feed On Dead Plant & Animal Remains (buzzards) Decomposers Fungi & Bacteria copyright cmassengale
Feeding Relationships Energy flows through an ecosystem in one direction from producers to various levels of consumers copyright cmassengale
Feeding Relationships Food Chain Simple Energy path through an ecosystem Food Web More realistic path through an ecosystem made of many food chains copyright cmassengale

Each Level In A Food Chain or Food Web is a Trophic Level. Trophic Levels Each Level In A Food Chain or Food Web is a Trophic Level. Producers Always The First Trophic Level How Energy Enters The System Herbivores Second Trophic Level copyright cmassengale
Each level depends on the one below it for energy. Trophic Levels Carnivores/Omnivores Make Up The Remaining Trophic Levels Each level depends on the one below it for energy. copyright cmassengale
