1 Sensitivity Sensitivity is the process through which living things detect and respond to changes in their environment. Animals detect information from their environment through their sense organs.

For instance, trees lose their leaves in autumn. 1 ●○○ CoMPARE the nutrition process in animals and plants. Animals feed on… Plants make their own… 2 ●●○ LISTEN.
