Earth is the only known planet to support life. There are beings who live, die and become part of nature again. The living organism can be differentiated from the inanimate entities on various parameters of life processes.
Life Processes
Photosynthesis can be defined as the synthesis of organic compounds (carbohydrates) from CO2 and H2O using radiant energy or solar energy by chlorophyll molecules.
The process of photosynthesis involves two phases: Light Reaction and Dark Reaction.
The following events occur during the process of photosynthesis:

Experiment Activity:
Heterotrophic organisms cannot prepare their food. They are dependent on plants, animals or on dead decaying organic materials for their food. Saprophytes derive their nourishment from dead decaying matter.
Holozoic nutrition is a mode of nutrition that involves swallowing solid food material. Ingestion, digestion, absorption, assimilation, and egestion are the various steps involved in holozoic nutrition.
