Apuntes

Study Guide – Chapter 3 – Ecology 1. What are ecological pyramids? Why do the levels get smaller as you move up the pyramid? 2. What happens to all the energy in an ecosystem? 3. Apply the 10 % rule of energy transfer 4. Know that unlike energy, nutrients are recycled 5. Describe the carbon, nitrogen and phosphorous cycles 6. Draw and label the phosphorous cycle. 7. Be able to label a diagram of the cycles 8. Cycles Vocab; photosynthesis, respiration, consumption, death and decomposition, deposition fossil fuel, combustion, nitrogen fixation, denitrification, Greenhouse effect and climate change 9. Describe carbon flux and know the four main carbon sinks on earth – hydrosphere, lithosphere, atmosphere and biosphere 10. Understand how carbon moves between these sinks: Photosynthesis – atmosphere to biosphere Respiration – biosphere to atmosphere Decomposition – biosphere to atmosphere or lithosphere Gaseous dissolution – ocean to atmosphere and vice versa Lithification – the compaction of carbon into fossils and rocks within the Earth’s crust (e.g. limestone) Combustion – releases carbon gases from burning to the atmos. Describe the greenhouse effect and how it is necessary for lif...
