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
