Nutrition Aim How do different living organisms obtain
Nutrition Aim: How do different living organisms obtain food?
Nutrition n Processes by which organisms obtain and use the nutrients required for maintaining life
Modes of Nutrition n Ways of obtaining and using nutrients Nutrition Autotrophic nutrition Herbivore Heterotrophic nutrition Carnivore Omnivore Decomposer
Autotrophic Nutrition A. Carry out by Autotrophs: are living things that can synthesize their own food from inorganic compounds and a usable energy source/sunlight Algae Flower Trees
Heterotrophic Nutrition n n Carry out by Heterotrophs: are living organisms that can NOT synthesize their own food and are dependent on other organisms for their food Caterpillar Monkey Lion
Types of Heterotrophs n Herbivores n Feed on plants only
Types of Heterotrophs n Carnivores n Feed on animals only
Types of Heterotrophs n Omnivores n Feed on both plants and animals
Types of Heterotrophs n n Decomposers Organisms feed on dead organisms or non-living organic matter n (e. g. fungi, bacteria) Bacteria Fungi
Importance of Decomposers n As decomposers n Allow essential materials (e. g. C, N) to be recycled in the ecosystem
