Homeostasis in Your Critter!
(Total Points 65)
Day and Time of your Interview: ______________________________________________
Fill out the following writing portion to use during Interview:
Part A: (5 pts)
1. Describe homeostasis in your own words. (2 pts)
2. Why is it important for organisms to maintain homeostasis? (2 pts)
3. What habitat does your critter live in? __________________________ (1 pt)
Part B: (28 pts)
List 2 additional environmental stresses that your critter would be subjected to in your habitat.
These should be short term stresses that they are able to overcome (they are not adapting or
evolving. They are responding and maintaining homeostasis) (2 pts)
a. Temperature
b. Viral Infection
c. __________________________________________
d. __________________________________________
Describe how your critter maintains homeostasis under each of the following conditions. For each
you must explain a behavioral (action or choice) and physiological (automatic) response.
1. My critter regulates internal temperature in response to heat and cold by … (10pts)
Behavioral: __________________________________________________________________________________________

Critter Project – Part 2 (Homeostasis)
Part D: (16 pts)
Drawing: You need to create an additional drawing or drawings that show the organ systems
responsible for the following functions:
Required Systems: (8 pts)
Gas exchange (ie: respiratory system) (4 pts)
Nutrient and fluid transport (ie: circulatory system) (4 pts)
AND…
PICK 2 ADDITIONAL SYSTEMS OF YOUR CHOOSING TO INCLUDE: (digestive,
nervous, urinary, reproductive) (8 pts)
______________________________________________
______________________________________________
Think about the functions of each of these systems and what internal structures
your critter has to carry them out. They should relate to the stresses you listed
above and how they overcome them.
