Transcript of "Nutrition"

  1. 1. Aim : How can we describe the types of nutrition in living things? Do now : 1. What is nutrition? 2. Why do living things need nutrition?
  2. 2. Nutrition : How an organism gets food ( nutrients, organic compounds ) and makes it available to the cells. Nutrients : useful portion of food: -sugar -amino acid -fat -starch Organic Compounds = FOOD!!!!!!
  3. 3. 2 TYPES OF NUTRITION 1. Autotrophic nutrition – Auto (self) trophic (refers to feeding and nutrition) “ Self feeding.” -Organisms that make their own organic compounds ex. Photo synthesis Chemo synthesis
  4. 4. a. Photosynthesis Photo (light) synthesis (creating, making) -Light is the source of energy for the production of food. -“Who?” ex. Plants
  5. 5. Autotrophs :
  6. 6. b. Chemosynthesis – Chemo (chemical) synthesis (creating, making) -Chemical activity is the source of energy for the production of organic compounds. Who? -organisms in environments that do not rely on the sun to make food. ex. Deep sea organisms
  7. 7. Photosynthesis Chemosynthesis
  8. 8. Chemosynthetic nutrition - Deep sea tube worms and arthropod

  10. 10. 2. Heterotrophic nutrition – Hetero: other trophic: (refers to feeding and nutrition) “ Fed by others.” - Heterotrophs: Organisms that eat organic compounds made by others. ex. Animals or animal-like protists called protozoa : amoeba, paramecium. Proto (first) zoa (animal, zoo)
  11. 11. Examples of heterotrophs paramecium
  12. 12. More heterotrophs….
  13. 13. Obviously, a _________________ . heterotroph!
  14. 14. Are you a heterotroph? Summary : 2 types of nutrition on Earth: 1. Autotrophic - photosynthesis - chemosynthesis 2. Heterotrophic
