  2.

  3. BUT…Does all living organisms have the IDEAL living conditions??

  4. Density-Dependent Factor Competition Predators Parasitism Disease (Virus, Bacteria) Density-Independent Factor Weather Natural Disasters Seasonal Cycles Human Activity What are Limits to Growth??

  5. Carrying Capacity • How many of a particular population a community can handle • What letter in the alphabet does this remind you of ??
