BIO101 STUDY GUIDE
Bio 101 Study Objectives for Exam 1
1. Know the characteristics of life
2. Understand how transfer of energy in an ecosystem works between the trophic levels
3. Know two basic cell types
4. Understand the basic steps of the scientific method and the proper design of an experiment. Including the statement of the hypothesis and use of controls.
Definitions
Energy
