Ecology Unit Test Review Guide (Turn in COMPLETED on test day, BEFORE the test for bonus points on the test!)

  1. List the levels of organization within the environment from largest to smallest (most specific).
  1. What level of organization would describe a flock of pigeons in a park?
  1. Complete a Venn Diagram comparing and contrasting biotic and abiotic factors.
  1. Label each of the following A (abiotic) or B (biotic).
