Be able to:
•Explain what carrying capacity is
•Determine the carrying capacity of population
•Explain what factors (biotic, abiotic, human)
cause increases and decreases in a population
Dotted line is the carrying
capacity (amount of organisms
the area can support)
When population graph is …
↗ Births > Deaths (resources
are plenty, predators
decreased, etc.)
↘ Births < Deaths (resources
are low; predators increasing,
etc.)
→ Level: Births = Deaths
(resources are right for number
of organisms)
