On day one of your field trip, you catch and tag 3 birds. When you come back a
few days later, you find that ¼ of the birds you caught on this day are marked.
How many birds are actually in the population?

• 8

• 16

• 14

• 12

What is the difference between daphnia and bosmina in terms of carrying
capacity (K)?

• Daphnia exceed K while using
  resources and energy reserves

• Bosmina store more energy and
  therefore are more sensitive to K

• Daphnia stay below K while using
  resources and energy reserves

• Bosmina exceed K while using
  resources and energy reserves

Which of the following would NOT contain a meta population based on its
geography?

• Set of islands (ex; Hawaii)

• Birds nesting in a recently deforested
  forest

• Plants and among the wetlands and
  swamps of New Orleans

• Deer population in an urban
  Pittsburgh town, with many
  roadways and bridges

Which of the following is a density-dependent factor that would limit K?

• An increased amount of nesting
  availability for birds

• A devastating earthquake

• An early spring that grows all of the
  local deer’s favorite plants

• A parasite that kills the rodents
  essential to a hawk’s diet
