AP Biology- Ecology
Across
- 7. Factors, resource availability and diseases that affect the population
- 9. Taxis, organisms that grow toward their energy source
- 10. Taxis, organisms that grow away from their energy source
- 11. Growth, when a population first grows slowly but then grows extremely fast
- 13. Capacity, the max amount of a population that an ecosystem can sustain
- 15. a negative relationship between two organisms where one benefits and the other is harmed
- 16. Levels, different levels of the food pyramid that describe the flow/depletion of biomass
- 17. organisms that use photosynthesis to produce biomass
- 19. organisms that consume dead organisms as a way of survival
- 21. Cycle, is the process by how carbon is stored in the ground and goes through organisms from the air
- 22. organisms that consume both producers and consumers
- 23. organisms that only consume producers
- 25. organisms that eat producers and slowly biomass depletes up the trophic levels
- 26. organisms that create energy to heat themselves
- 27. a positive relationship between two organisms where they both mutually benefit
- 28. a relationship between two organisms where one benefits and the other is unaffected
Down
- 1. Factors, nonliving factors that contribute to the health of a population
- 2. the non-directional movement of an organism
- 3. Growth, when a population is reproducing faster than it is dying off
- 4. the directional movement of an organism
- 5. species, species that reproduce slowly but live longer life-spans
- 6. is the state that the body wants to be in where it is balanced
- 8. Factors, natural disasters that affect the population
- 12. Growth, when a population at first grows fast but then reaches its carrying capacity
- 14. species, species that reproduce quickly but live shorter life-spans
- 18. organisms that only consume consumers
- 20. organisms that use heat from outside sources
- 24. Factors, living factors that contribute to the health of a population
