|
Process by which parents produce offspring |
Reproduction |
|
|
What are the three key features of living things? |
1. All living things need energy and nutrients 2. Each living thing has the capacity to sense and respond to change (homeostasis) 3. DNA is passed to offspring during reproduction |
|
|
What eventually happens to energy that enters the world of life? |
It flows out of it mainly as heat released back into the environment |
Think of the flow of energy |
