Some flatworms have clusters of nerve cells called ganglia that control their nervous system. Ganglia are distributed throughout the body and help coordinate the flatworm's movements and responses to stimuli.
The total changes that take place during physiological processes are called homeostasis. Homeostasis involves the regulation of various body functions to maintain a stable internal environment despite external changes.
The ability to respond to a stimulus is called irritability or responsiveness. It refers to an organism's ability to detect and react to changes in its environment.
Animals whose body temperatures do not change much despite the temperature of the environment changing are called ectotherms. This ability allows some animals to live in harsh environments.

Only some flatworms, usually the smaller species, have small "hairs" called cilia on their skin.
Adaptation
The human body self-regulates to maintain a stable internal environment despite changes in the external environment is a process called homeostasis. They begin by looking at how the human body regulates temperature and the value of a feverin fighting infection.

All animals live in the environment, in a niche of the environment called their habitat. Changes to the environment can destroy a habitat resulting in the species comprising that habitat to die out.
The lizard that changes color is called a chameleon. They have specialized cells called chromatophores that allow them to alter their skin color to blend in with their environment or display their mood.
biomass
The life process by which organisms respond to changes in the environment is called "stimulus response." Organisms sense changes in their environment through stimuli and react in ways that help them survive and thrive. This process is essential for adaptation and survival in different environments.
