What is Life?
What is life? Does this seem like a strange question to you? Well,
let's think about it. If you had to explain to someone what "life" is,
what would you tell them?
Do all living things move? Do they eat and breathe? Even though we all
seem to know what is meant by saying something is
"alive", it's not very easy to describe what "life" is. It's almost as hard as describing where life came from
The study of life is called "biology" and the people who study it are
"biologists". They even have a tough time describing what life is! But
after many years of studying living things, from the
mold on your old tuna sandwich to monkeys in the rainforest, biologists have
determined that all living things, do
share some things in common:
1) Living things need energy
2) Living things grow and develop
3) Living things respond to their surroundings
4) Living things reproduce
