Nutrition Aim: How do different living organisms obtain food?
2
Nutrition Processes by which organisms obtain and use the nutrients required for maintaining life
3
Modes of Nutrition Ways of obtaining and using nutrients Nutrition
Autotrophic nutrition Heterotrophic nutrition Herbivore Carnivore Omnivore Decomposer
4
Autotrophic Nutrition
A. Carry out by Autotrophs Autotrophs: are living things that can synthesize their own food from inorganic compounds and a usable energy source/sunlight Trees Flower Algae
5
Heterotrophic Nutrition
Carry out by Heterotrophs Heterotrophs: are living organisms that can NOT synthesize their own food and are dependent on other organisms for their food Caterpillar Lion Monkey
6
Types of Heterotrophs Herbivores Feed on plants only
7
Types of Heterotrophs Carnivores Feed on animals only
8
Types of Heterotrophs Omnivores Feed on both plants and animals
9
Types of Heterotrophs Decomposers
Organisms feed on dead organisms or non-living organic matter (e.g. fungi, bacteria) Fungi Bacteria
10
Importance of Decomposers
As decomposers Allow essential materials (e.g. C, N) to be recycled in the ecosystem
11
Practice Correctly categorize the following organism’s mode of nutrition and explain why. Which mode of nutrition am I? Answer: Heterotrophic nutrition Specifically, Carnivore Why? Because I only eat meat.
