Answer
1. The nervous system needs to detect stimuli for survival, as it allows the body to respond to threats in the environment.2. The nervous system also needs to detect stimuli to maintain homeostasis, as it helps to regulate the body's internal environment.
Explanation
## Step 1:The nervous system is responsible for receiving and interpreting information from the environment and the body. This information comes in the form of stimuli, which can be internal (such as hunger or pain) or external (such as temperature or light).## Step 2:The first reason why it's important for the nervous system to detect stimuli is for survival. The nervous system allows us to respond to threats in our environment by triggering a physical response, such as moving away from danger or preparing the body to fight or flee.## Step 3:The second reason is for maintaining homeostasis. The nervous system helps to regulate the body's internal environment by responding to changes in conditions such as temperature, pH, and nutrient levels. For example, if the body is too hot, the nervous system can trigger sweating to cool it down.
