Question

Name three conditions needed for life as we know it to exist

Answer 1

Strange as it may seem, there isn't really one standard definition of life. We can't say that life requires something as specific as breathing or growing; there's just too much variety to living things to nail down one specific criterion.

What we can do is talk about some things that all living things on Earth share: They're carbon-based; they require water; they use energy. Perhaps most important for survival, they can grow or reproduce in some way.

Answer 2

Movement of any type could be taken as an indication of life.
For eg growth in plants.

Three essentials for a living thing to live are oxygen,food and shelter.
