Every organism NEEDS 4 things to live.

1. Water. Self-explainable.

2. Food. It's an energy source.

3. Living Space. All organisms need space to obtain food and water.

4. Stable Internal Conditions. Organisms must be able to keep their body stable, even when outside conditions change. (Like System Regulation a.k.a. Regulation of body temperature.)

Everything else, is what certain species need to survive. But those 4 are the basics for all organisms. EVERY living thing needs these things.
