2.76 Sensitivity

Understand the organisms are able to respond to changes in their environment.

Stimuli (changes in the environment) can be either light, temperature, pressure or chemicals, in order to detect the changes in the environment, organisms are required to have receptors and in order to respond, organisms have effectors such as muscle/glands. It is the response that ensures the organism is able to survive the changes in the environment.
