What are the 3 basic functions of living things?

the three functions (main functions) of living things are:

1. Nutrition: all living things have ways of taking in the substances they need to grow and survive.

2. Relation: Living things have a relationship with the environment that surrounds them. Humans use their senses (seeing, hearing, smelling, tasting, touching) to relate with the world.

3. Reproduction: all living things are born, live for a period of time and then die.

The main function of any living organism is to propagate, while some organisms have symbiotic relations with others there main function is self preservation.
