Chapter6.1 Types of Nutrition
(autos : self ; trophos : feed)Produces own food from raw, simple inorganic substances by :
Photosynthesis
Green plants (photoautotrophs) manufacture their own food from carbon dioxide and water using sunlight as a source of energy
Chapter 6: Nutrition
Using light energy

Chapter6.1 Types of Nutrition
Chemosynthesis
Certain bacteria (chemoautotrophs) produce food by oxidisinginorganic substances such as hydrogen sulphide and ammonia
Chapter 6: Nutrition
Using chemical energy

Chapter6.1 Types of Nutrition
Unable to manufacture own foodMust obtain the nutrients from other organisms
Feed on dead and decaying organic matter
Digest their food externally before absorbing the nutrientsinto their bodies (extra cellular digestion)
Saprophytism
Chapter 6: Nutrition
(hetero : other)

Chapter6.1 Types of Nutrition
Parasitism
Obtain food by living on and absorbing readily digested food from the body of another organism, called the host

Chapter6.1 Types of Nutrition
Holozoic nutrition (holo : like ; zoon : animal)
Carnivorous –Carnivores(animal eaters)
Feed by ingesting solid organic matter which is digestedand absorbed into their bodies
Omnivorous –Omnivores
(both plant and animal eaters)
Herbivorous –Herbivores(plant eaters)
