4. Animals and Their Abiotic Environments
A habitat includes all biotic and abiotic factors
Animals operate best when in their typical tolerance range
The range of optimum defines the conditions under which an animal is most successful
When does a factor become limiting?

Periods of decreased body temperature and metabolism in animals
Survival mechanism to help animals through harsh conditions
Torpor – Daily
Hibernation – Weeks or Months
Winter Sleep – Months
Aestivation – Months or Years

8. Interspecific Interactions
Predation
Competition
Coevolution
Symbiosis
Coloring (camouflage, cryptic coloration, countershading, aposematic coloration)
Mimicry
