Life Process

The processes together that provide maintenance to living organism must be regular and these are the process that is very important for any organism to stay alive. This maintenance process is called life process these include processes like Nutrition and respiration. Even if we are sitting idle or sleeping we need maintenance for a living.

Nutrition

The process in which an organism consumes food in order to utilize the same to produce energy so that the same can be utilized for our growth and maintenance. This energy also helps us to remove waste from our body.

1. Autotrophic Nutrition: – The word autotrophic is made up two words where auto means self and trophos means nourishment. So the autotrophic nutrition is simple nutrition that is obtained from inorganic substances like cordon dioxide and water. The process through which Autotrophs take in substance from outside and convert it into stored forms of energy. This process is also termed as Photosynthesis. The raw materials used in this process are carbon dioxide and water. The solar energy or light energy is converted into chemical energy

Let’s try to explain the same step by step

• Light energy/solar energy absorbed by chlorophyll
• The Light energy is then converted into chemical energy, hence splitting the water molecules
• Carbon dioxide is then reduced to carbohydrates.
