PPT-Photosynthesis Autotrophs & Heterotrophs

Autotrophs organisms use can make their own food Some autotrophs capture light energy from the sun in the process of photosynthesis Heterotrophs obtain energy from the foods they consume. *. Photosynthesis. – process of capturing light . . energy. from the sun to convert water & CO. 2. . . into oxygen and high energy carbohydrates . (food, ex: glucose, starch, & other sugars). The History of Classification. In the 1700’s, Linnaeus separated all life into 2 Kingdoms: Plants and Animals.. More kingdoms added as knowledge of the diversity of organisms increased.. We currently have 6 Kingdoms. . Bryanna Wolfe. ECE 2320. October 2012. Start Here. Objective:. . When you get hungry you might decide to raid the cookie jar or ask your mom to make you a sandwich. You do this because humans and animals get energy from the foods they eat. By . Ms. Megan Black. Photosynthesis. Photosynthesis is the process of making food by plants. The essential ingredients in making this food are sunlight, the chlorophyll that is present in green plants, water and carbon dioxide in the air. . Textbook pages 97 – 103. Photosynthesis . process used by plants using light energy to create sugar (glucose, C. 6. H. 12. O. 6. ) from carbon dioxide (CO. 2. ) and water (H. 2. O). oxygen gas (. O. 1. ENERGY AND LIFE. OBJECTIVES: 8.1. Explain where plants get the energy they need to produce food.. Describe the role of ATP (adenosine . triphosphate. ) in cellular activities.. 2. Energy is the ability to do work.. Unit 3 . Think back to Energy Transfer…. Living things use energy for . Growth. Repair. Reproduction. Metabolism. The collection of reactions that occur in a cell . Metabolism. Involves either:. .

Protists. are eukaryotes that can not be classified as animals, plants or fungi.. Name means: “Drifters” or “Wanderers. ”. So. . .are they autotrophs. or heterotrophs?. They can be either one!. Autotrophs vs. Heterotrophs. Most autotrophs use sunlight to make energy. Heterotrophs. 8-1: Energy & Life. What is energy?. The ability to do work.. What is the difference between autotrophs & heterotrophs?. . Autotrophs = make their own food. . Heterotrophs = can’t make their own food; must eat other organisms. What is the . ideal combination of factors . for the . maximum . rate of photosynthesis? . enough light. . enough carbon dioxide. . ideal temperature . (not too hot or cold). How is the rate affected if one of these factors is . 7. th. Grade Science. P.S. DuPont Middle School. The History of Classification. In the 1700’s, Linnaeus separated all life into 2 Kingdoms: Plants and Animals.. More kingdoms added as knowledge of the diversity of organisms increased.. Ps. Overview: The Process That Feeds the Biosphere. Photosynthesis . is the process that converts solar energy into chemical energy. Directly or indirectly, photosynthesis nourishes almost the entire living world.
