The most important criterion for determining
whether something is alive is movement.
All living things exhibit movement without external
assistance.
Movement includes both visible movements of
body parts and less visible molecular movements
within cells and tissues, which are essential for life
processes.
How to know if something is                 or not?

Life Processes
Nutrition: The process of acquiring food and utilizing it for
life processes.
Respiration: The process in which food is metabolized in
cells with the help of oxygen to release energy.
Transportation: The process of carrying substances such
as food, oxygen, water, and waste products between
different parts of the body.
Excretion: The process of eliminating waste products from
the body.
The basic life processes include:

Importance of Carbon-Based Molecules: Life on
Earth relies on carbon-based molecules, and
most food sources are composed of such
molecules. The primary external raw materials
needed by living organisms are food, water,
and air.
Nutrition is the process through which organisms
take in food and utilize it for various purposes such
as body growth, repair, energy production, and
overall development.
