Test

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

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
