Across
- 2. Competition Members of the same species compete with each other
- 7. are Top predators least energy Rule Only about 10% of energy is passed to the next level the rest is lost as heat
- 10. Photosynthesis plants absorb CO₂, respiration animals release CO₂, decomposition, combustion
- 13. Organisms depend on both biotic and abiotic for survival Changes to one can affect the entire ecosystem
- 16. are Carnivores and also omnivores
- 18. Evaporation, condensation, precipitation, runoff
- 19. Both species benefit bees and flowers
- 20. Nonliving parts water, sunlight, temperature, soil, air, minerals
- 21. A linear sequence showing how energy and nutrients flow from one organism to another
Down
- 1. Nitrogen fixation bacteria convert N₂ to usable forms, uptake by plants, consumption by animals, decomposition returns nitrogen to soil/air
- 3. organism that gets hunted by predator
- 4. are Herbivores
- 5. One organism hunts prey
- 6. One benefits, the other is unaffected barnacles on whales
- 8. Matter is red in ecosystems energy flows in one direction from sun to producers to consumers to decomposers
- 9. Living parts of an ecosystem plants, animals, bacteria, fungi
- 11. Plants most energy
- 12. Food webs show how multiple food chains overlap and how organisms often have more than one food source or predator
- 14. Shows the energy flow through trophic levels in an ecosystem
- 15. One benefits parasite, the other is harmed host, tapeworm, in a human
- 17. Competition Different species compete for the same resources food, space
