This quiz was written to test the material on my ecology unit called, Ecosystems and the Biosphere: Energy Flow and the Recycling of Matter.
This document can be used as a quiz, as a homework assignment or as test review. The document contains 38 questions. There are 25 fill in the blank questions, 11 matching questions and 2 short answer questions. Answer key is provided.
This quiz is appropriate for biology or life science students in grades 7 - 12. I use this quiz as a quick and easy check for understanding and to make sure that my students are keeping up with their nightly studying.
Topics covered in this lesson are:
1. Energy Flow Through the Ecosystem: Sunlight as a source of energy, importance of photosynthesis, conversion of energy into glucose and other organic compounds.
2. Autotrophs, producers, examples of autotrophs, chemoautotrophs and chemosynthesis.
3. Heterotrophs, consumers, examples of heterotrophs, herbivores, carnivores, omnivores, detritivores, decomposers, the essential nature of decomposition.
4. Feeding Relationships: One way flow of energy through the ecosystem, food chains, examples of food chains, food webs, trophic levels, primary producers, primary consumers, secondary consumers, tertiary consumers.
5. Productivity of the Ecosystem: Two ways to measure productivity, gross primary productivity, the role of glucose in productivity, biomass, net primary productivity, factors that determine productivity in both terrestrial and aquatic ecosystems.
6. Energy transfer between trophic levels, ecological pyramids, percentage of energy that moves up to the next trophic level, reasons why the transfer of energy is so low.
7. Given a hypothetical food chain, the student will identify the autotroph, the primary consumer, secondary consumer, and tertiary consumer as well as calculate the amount of energy passed to each trophic level.
8. Ecosystem recycling: the recycling of matter, the essential need to recycle carbon, nitrogen, water, and phosphorus, biogeochemical cycles.
9. Water Cycle: Location of water, evaporation, precipitation, transpiration, condensation, steps to water cycle, students will complete a diagram of the water cycle.
10. The Carbon Cycle: The importance of carbon to organic compounds, the role of photosynthesis and cellular respiration in the carbon cycle, the role of erosion and volcanic activity in the carbon cycle, decomposition, burning of fossil fuels, steps to the carbon cycle, the student will label a diagram of the carbon cycle, the human impact on the carbon cycle.
11. The Nitrogen Cycle: The importance of nitrogen in building proteins and nucleic acids, nitrogen fixation, ammonification, nitrification, denitrification, assimilation, the role of various bacteria in the nitrogen cycle, students will label a diagram of the nitrogen cycle.
12. The Phosphorus Cycle: The importance of phosphorus to ATP and nucleotides, the movement of phosphorus through the ecosystem.
13. Limiting nutrients
The download will include both a Word document as well as a pdf form of the quiz.
