Describe producers, for example, phytoplankton’s role in the Oxygen Cycle.9. What process is responsible for returning carbon to the soil and releasing CO2 back to theatmosphere?10. Carbon is stored in fossils fuels such as _______________, ________________, and___________________.11. Compare and contrast photosynthesis and chemosynthesis.How are they similar? How are they different?12. Describe how nitrogen is necessary for life on Earth. 13. Complete the chart.Term Definition ExamplesProducerConsumer• Herbivore• Omnivore• Carnivore• Detritivore• Decomposers14. Using the terms listed below, create AND label a food chain. Include arrows showing theflow of energy.Sun Producer SnakeMouse Owl Emits energyConsumer (use 3 times) Grass HerbivoreCarnivore (use 2 times)15. Matter and energy flow through an ecosystem. Sort the following terms based on how itflows through the ecosystem:Water, Carbon, Nitrogen, Energy, OxygenOne Direction Cycles 16. Describe how a FOOD WEB is different than a FOOD CHAIN.17. Is a food web or food chain a more accurate description of the energy flow within anecosystem. Why?18. Create an energy pyramid. Place the organisms in the correct level:o Rabbit, flowers, mice, grass, hawk, treesLabel the trophic levels:producer (trophic level 1), primary consumers (trophic level 2),and secondary consumers (trophic level 3)______________________________________________________________19. If 1000 kcal were available at the producer (trophic 1) level of the energy pyramid, how many kcalwould be available at the secondary consumer (trophic 3) level?20. What type of energy is stored in the organisms at each trophic level?
