1 Life Processes

The basic function performed by living organism to maintain their life are called life processes.

The basic life processes are:

1) Respiration

Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP.

The process of acquiring oxygen from outside the body and to use it in the process of break down of food sources for cellular need is called respiration.

2) Nutrition

It is a process by which organism obtain and utilise the nutrients to perform biological activities.

3) Transport

It is a process in which the substance synthesised or absorbed in one part of body are carried to other part of body.

4) Excretion

It is the process involved in removal of excess wastes from body.

5) Control and coordination

It is the process which helps the living organism to receive information from the surrounding and behave accordingly.

6) Growth

The permanent increase in size of the organism.

7) Movement and locomotion

In this process, the organism either move from one place to another or move its body parts while remaining at the same place.

8) Reproduction

The making of more organism from the existing ones.
