                             Homework & Problems

CHAPTER 1
1. What are the 7 properties of life?

2. Provide a brief description of each of the levels of Biological Organization.

3. Describe each level of Biological Organization in terms of the next “lower” level.

4. Name the 2 main sources of energy for producers

5. Where do consumers get their energy?

6. Which is more important to an ecosystem? Producers or consumers. WHY?

7. Why do plants have more in common with fungi than bacteria?

8. What is the relationship between Genes, chromosomes & DNA?

9. Consider the phrase: “The first million is the hardest to make”. This implies that subsequent
   millions of income are easier to make after the first million has already been made. This is an
   example of which type of feedback? Why?

10. When you flush a toilet, water begins to fill the tank and lift a sensor. Once the sensor (floating in
   the water) reaches a certain level, the water flow ceases, preventing an overflowing of the tank.
   This is an example of which type of feedback? Why?

11. How does D. Archaea differ from D. Bacteria?

12. How do D. Archaea & D. Bacteria differ from D. Eukarya?

13. Explain why “editing” is a better metaphor for how natural selection acts on a population’s
     heritable variation than “creating”.
