Function: To achieve thermal regulation through heat exchange. Strategy: The hollow core hair follicles reflect light and trap heat.
Mechanism: Each hair shaft is pigment-free and transparent with a hollow core that
scatters and reflects visible light, much like what happens with ice and snow. Polar bears have black skin under which there is a layer of fat that can measure up to 4.5 inches. On land the polar bear’s thick fur coat, not its fat prevents nearly any heat loss. In fact, adult males can quickly overheat when they run. In the water, polar bears rely more on their fat layer to keep warm: wet fur is a poor insulator. This is why mother bears are so reluctant to swim with young cubs in the spring: the cubs just don’t have enough fat.
Design Principle: Our design must regulate temperature regardless of external elements

PHYTOPLANKTON
Function: To produce its own food and energy. Strategy: Conversion of energy into food.
Mechanism: Phytoplankton inhabiting well-lit surfaces of freshwater use photosynthesis to produce energy in the form of life sustaining sugars. Chloroplasts, known as the “food
producers of the cell,” convert energy from the sun into sugars. These single celled organisms also convert inorganic compounds and carbon dioxide that is extracted directly from the water (NOAA, 2014).
Design Principle: Our design must efficiently utilize sunlight, so that it produces food and
nutrients essential to other organisms.

RACCOON (Procyon Lotor)
Function: To utilize a large variety of food types.
Strategy: Raccoons are resourceful, sensitive and roam widely which allows them to
gather a large variety of nutrients and adapt to changing conditions quickly.
Mechanism: Being generalist, Raccoons can eat a large variety of foods to fulfill their
nutritional needs. This allows them to adjust to change in conditions quickly and to survive, even thrive, in many different environments including human cities and towns (Rulison, E. L., Luiselli, L., & Burke, R. L. 2012).
Design Principle: Our design must utilize a variety of nutritional sources, so that adaption
to changing conditions can happen quickly.
