2.76 Sensitivity

Understand that organisms are able to respond to changes in their environment 

1. Characteristics of life = MRS GREN

S = Sensitivity (how you respond to changes in the environment).

2. Types of changes: Light levels, Temp levels and Chemical Levels.

3. To detect changes, organisms have receptors. 
4. To respond to changes, organisms have effectors.
5. Response = the organism is able to survive  the changes in the environment.
