Unit A-Chapter 3-Lesson 1 Notes

What Are Adaptations?

Life Processes

1.) All living things carry out 6 life processes:

• Taking in energy
• Releasing energy in food
• Using Energy for body processes
• Producing and excreting wastes
• Responding to change in the environment
• Reproducing

2.) All organisms need energy to carry on life processes.

3.) Plants get their energy from the sun.

4.) Animals get their energy by eating other organisms

Adaptations

1.) A trait is a characteristic of an organism

Adaptations are inherited traits that help a species survive in its environment.

2.) Species do not adapt quickly.  Adaptations take a long time to develop.  Generation after generation reproduces before a trait becomes an adaptation of an entire species.
