Final answer:
A spider catching its prey in a web demonstrates homeostasis by responding to stimuli, a process crucial for maintaining its internal environment by securing food for survival.
Step-by-step explanation:
When a spider catches its prey in a web, this can be seen as an example of homeostasis because it is responding to stimuli. The spider detects its prey due to the vibrations in the web, which activates its response system to approach and secure the prey. This action falls under the concept described by 2.C.1 Organisms use feedback mechanisms to maintain their internal environments and respond to external environmental changes. Through this process, the spider is able to regulate its internal environment by ensuring that it has food, which is necessary for its survival, growth, and energy balance.
