Review for Exam• Same format• Topics
– Deep Sea– Subtidal Benthic– Intertidal– Meiofauna– Estuaries and Salt Marshes– Don’t forget Oceans in the News
• Website will be up-to-date by tomorrow AM– Outlines and ppt files (there already)– Practice questions
Review for Exam
• Think about similarities and differences in these different habitats– Abiotic factors– Biotic factors– Adaptations– Types of organisms
The Review Game• If you want to play,
pick up one A,B,C, and D (these are not grades!)
• Stand up• Multiple choice
questions – hold up your answer choice; sit down if you are incorrect
• Last 5 left standing will win bonus points!
