Across
- 4. The rate at which an ecosystem accumulates energy or biomass, excluding the energy it uses for the process of respiration.
- 6. when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on.
- 10. the visual summary of the feeding interactions within a community.
- 12. displays the biomass of each trophic level.
- 15. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
- 17. a sequence in which energy is transferred from one organism to the next as each organism eats another organism.
- 19. the total production by all producers in an ecosystem.
Down
- 1. states that when energy is converted from one form to another in a physical or chemical change, no energy is created or destroyed.
- 2. shows the energy available at different trophic levels in an ecosystem.
- 3. the persistence of a community or ecosystem in the face of disturbance
- 5. states that when energy changes from one form to another, we always end up with lower-quality or less usable energy than we started with.
- 7. the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals.
- 8. the amount of energy that is transferred between trophic levels.
- 9. the production of organic matter, or biomass, by photosynthetic or chemosynthetic autotrophs.
- 11. shows the energy available at different trophic levels in an ecosystem.
- 13. position in a food web.
- 14. an inclusive term that encompasses all aspects of biological diversity
- 16. the production of biomass via the consumption of another organism by a heterotrophic organism.
- 18. solar energy is converted into chemical energy and then into mechanical energy.
