Chapter 3
1. Define Matter. Distinguish between the following: atoms, ions, molecules, isotopes,
protons, neutrons, electrons, atomic number. List three physical properties of matter.
2. What is the law of conservation of matter?
3. What are the building blocks of Nature? What two chemical forms is matter found in?
4. Define chemical formula. Distinguish between molecular compounds held together by
covalent bonds and ionic compounds held together by ionic bonds. Describe a hydrogen
bond.
5. Define organic compound. List four important organic polymers and their building
blocks. Contrast organic and inorganic. Give two examples of inorganic compounds.
6. Distinguish between high-quality and low-quality matter.
7. Describe how the law of conservation of matter and energy governs normal physical and
chemical change. Explain the phrase” There is no way”.
8. Describe why the law of conservation of matter and energy is necessary to govern nuclear
changes. Distinguish among gamma rays, alpha particles, beta particles, nuclear fission
and nuclear fusion.
9. Define energy. Distinguish between kinetic and potential energy, ionizing and nonionizing radiation, high quality and low quality energy
10. Summarize the first and second laws of thermodynamics and give and example of each.
11. Describe the implications of the law of conservation of matter and the second law of
energy for high-waste, matter – recycling and low-waste societies.
Chapter 4
1. Define ecology. List and distinguish among the five levels of organization of matter that
are the focus of the realm of ecology.
2. What are the major parts of the Earth’s life support system. Briefly describe how the sun,
gravity, and nutrient cycles sustain life on Earth. Compare the flow of matter and the
flow of energy through the biosphere.
3. Do ecosystems have distinct boundaries? Explain what an ecotone is.
4. Define abiotic component of an ecosystem. List three important physical factors and three
important chemical factors that have large effects on ecosystems.
5. In your own words explain the law of tolerance. Draw the diagram. Compare the
limiting factors in terrestrial and aquatic ecosystems
6. Define biotic component of an ecosystem. Distinguish between producers and
consumers. List and distinguish four types of consumers. Distinguish among
scavengers, detritus feeders and decomposers. Distinguish between photosynthesizes and
chemo synthesizers; aerobic respiration and anaerobic respiration.
7. Distinguish between food chains and food webs; grazing food web and detrital food web.
Apply the second law of energy to food chains and pyramids of energy, which describe
energy flow in ecosystems. Explain how there may be exceptions to pyramids of
numbers and biomass, but not energy.
8. Evaluate which ecosystems show the highest average net primary productivity and which
contribute most to global net primary productivity.
9. Summarize the hydrological cycle. Describe the unique properties of water and how it
contributes to life. Summarize the human impact on the water cycle.

heating of the Earth’s atmosphere. Summarize the human impact on the carbon cycle.
11. Summarize the nitrogen cycle. Describe a connection between plants and the atmosphere
that makes nitrogen useable for humans and other consumers. Summarize the human
impact on the nitrogen cycle.
