2Section1: Energy Flow in Ecosystems Use sunlight in photosynthesisPlants, algae, and some bacteria capture solar energyMake carbohydrates (energy + H2O + CO2)Used by organism and transferred when eatenUsed to move, grow, digest, and reproduce *Life Depends on the Sun
3Section1: Energy Flow in Ecosystems Producer makes own food = autotrophicConsumer gathers energy from other organisms = heterotrophic *Producers to Consumers
4Section1: Energy Flow in Ecosystems In a Hydrothermal Vent (opening under ocean floor)No sunlight; no photosynthesis; bottom of oceanBacteria make food from hydrogen sulfides escaping from mantleEcosystem built from these autotrophs *Exception to the Rule
5Section1: Energy Flow in Ecosystems Class Chart *What Eats What?
6Section1: Energy Flow in Ecosystems Opposite of photosynthesisBreaking down food using OxygenExcess energy is stored *Cellular Respiration
7Section1: Energy Flow in Ecosystems Marsh Mallow LabWhy is a pyramid used?What do primary, secondary, and tertiary mean?Why does only 10% transfer? *Energy Transfers
