Mode of nutrition.pptx

This ppt describes the mode of nutrition in plants and animals. The mode of nutrition is broadly divided into two categories: autotrophic mode and heterotrophic mode. The autotrophic mode has two types such as photosynthesis and chemosynthesis. In this ppt, only photosynthesis is discussed. The definition of nutrition is provided. The definition of photosynthesis is given with some examples.
Heterotrophic nutrition has three types such as parasitic nutrition, saprophytic nutrition and holozoic nutrition. Each section is defined with appropriate examples. Holozoic nutrition in animals has three categories such as herbivores, carnivores and omnivores. All the above mentioned are explained with examples.

1. Mode of Nutrition Presented by - Sheuli Sarkar

2. Table of Contents 01 Definition and its type 02 Autotrophic Here you could describe the section 03 Here you could describe the section 04 Holozoic Here you could describe the section Introduction Heterotrophic

3. Introduction 01 Nutrition is the process of taking in food and converting it into energy and other vital nutrients required for life

4. Types of nutrition Autotrophic Mode Nutrition Heterotrophic Mode Prepares food on their own Take food from others

5. Autotrophic Nutrition 02

6. Autotrophic Nutrition Autotrophic nutrition is a process where an organism prepares its own food from a simple inorganic material like water, mineral salts and carbon dioxide in the presence of sunlight.

7. Autotrophs example Plants Cactus Jade plant Rose Algae Green algae Red algae Bacteria cyanobacteria

8. Heterotrophic Mode 03

9. Heterotrophic Mode Heterotroph is an organism that is unable to synthesize its own food, and therefore, has to rely on other sources, specifically plant and animal matter. Types Holozoic Nutrition Saprophytic Nutrition Parasitic Nutrition

10. Holozoic Nutrition 04

11. Holozoic Nutrition Holozoic nutrition (Greek: holo-whole ; zoikos-of animals) is a type of heterotrophic nutrition that is characterized by the internalization (ingestion) and internal processing of liquids or solid food particles . Examples - Human Amoeba Cat Dog

12. Saprophytic Nutrition 05

13. Saprophytic Nutrition It is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter. It occurs in saprotrophs, and is most often associated with fungi (for example Mucor) and soil bacteria Examples- Rhizopus Yeast Agaricus

14. Parasi tic Nutrition 06

15. Parasi tic Nutrition Parasitic Nutrition is a mode of heterotrophic nutrition where an organism (known as a parasite) lives on the body surface or inside the body of another type of organism (known as a host) . The parasite obtains nutrition directly from the body of the host. Examples- Lice Tapeworm Vampire bats

16. Animals taking Holozoic nutrition 07

17. Holozoic animals an organism that mostly feeds on plants . Examples - Cows Elk Herbivores an organism that mostly eats meat, or the flesh of animals . Examples - bear Canidae Carn ivores an organism that eats plants and animals . Examples - Human Foxes Omn ivores
