Chapter 5 - Life Processes - Nutrition

Click here to go to Home Page Chapter 5 Life Processes Life Processes :- Life processes are the basic activities and functions that are essential for an organism to stay alive. These include processes like nutrition , respiration , transportation , excretion , growth , reproduction , and response to stimuli . All living organisms carry out these processes to maintain and sustain life.   Nutrition :- It is the process by which an organism obtains nutrients from food and utilizes them to obtain energy, for building and repairing its tissues. Modes of Nutrition 1. Autotrophic nutrition 2. Heterotrophic nutrition Autotrophic nutrition - The mode of nutrition in which organisms produces their food by themselves such as green plants, green algae, etc is known as autotrophic mode of nutrition. Photosynthesis The process by which green plants prepare their food by themselves with the help of carbon dioxide, sunlight and water in presence of chlorophyll known as photosyn...
