Mound facilitates gas exchangemound-building termites
The internal structure of above-ground macrotermite mounds facilitates gas exchange in the below-ground nest by harnessing external wind energy
Nest maximizes solar heat absorptionwood ants
Wood ants maximize solar heat absorption by their nest via the optimum angle of orientation.
Folds allow efficient leaf deploymentplants
Leaves of plants maximize time exposed for photosynthesis by using various packaging schemes to fold the large leaves within the buds so they can begin photosynthesizing upon deployment.
Colonies maintain temperature and humiditySouth American grass-cutting ant
Colonies of South American grass-cutting ants maintain temperature and humidity via a thatched nest and systematic arrangement of nest material.
Mound passively heats/coolscompass termite
Mounds of compass termites provide heating and cooling at appropriate times of day thanks to orientation with respect to the sun.
