Answer:
- Each kind of change in the environment evokes an appropriate movement in response by a living organism.
for eg: when we want to talk to our friends in class, we whisper rather than shouting loudly. - Clearly the movement to be made depends on the event that is triggering it.
- Therefore, such controlled movements must be connected to the recognition of various events in the environment, followed by only the correct movement in response.
- In other words, living organisms must use systems providing control and coordination.
