draw a flowchart to show different modes of nutrition and its types their definitions and examples
Answers
Answer:
The basic process of obtaining food is called the nutrition. The various ways by which this nutrition is obtained are called the modes of nutrition. These are mainly classified into two types:
- Autotrophic Nutrition
- Heterotrophic Nutrition
Explanation:
Autotrophic Nutrition:
The autotrophs acts as the producers and prepare their own food by using carbon dioxide from air, water from the roots, sunlight and chlorophyll for e.g., chromatium, rhodobacter capsulatus. Some autotrophs also prepare their food by harnessing energy from the oxidization of inorganic chemicals for e.g., methane bacteria. Two types of autotrophic nutrition are phototrophic nutrition and chemoautotrophic nutrition.
Heterotrophic Nutrition:
Some organisms which cannot prepare their own food and depend on green plants and other organisms to convert high energy into their food. Examples: protozoans, liver fluke, decomposer protists, symbiodinium on corals. These could be classified as parasitic, holozoic, saprophytic and mixotrophic.
Pictorial representation of different modes of nutrition, with its types and examples:
Answer: The modes of the nutrition are of two types are:
1. The Autotrophic
2. The Heterotrophic
1. The Autotrophic- organism which make their own food with the help of Co2 and O2.
examples are green plants, algae, bacteria.
2. The Heterotrophic- organism which cannot make their own food they depend to other like green plants.
examples are fungi,yeast.
