1. Ecology Review Game
Ecology test review

2. What is the definition of biodiversity?
The number of different kinds of organism in an area

3. What is the greatest threat to biodiversity?
Habitat loss

4. How are biotic factors different from abiotic factors?
Biotic are living and abiotic are non-living

5. What are three examples of abiotic factors?
List of three non-living things

6. What do decomposers do?
Recycle nutrients

7. What are some examples of decomposers?
Bacteria and fungi (mushrooms)

8. Is the following example a niche or habitat. Explain
Is the following example a niche or habitat? Explain. A bird nesting in a tree
Habitat; it describes where an organism lives

9. What are 4 processes that are part of the water cycle?
Evaporation, precipitation, condensation, runoff, accumulation, transpiration, seepage (groundwater)

10. In the water cycle, what is one way that water moves from a biotic to an abiotic factor?
Transpiration (from plants to the air)

11. Oxygen and carbon dioxide are cycled in the carbon cycle by which two processes?
Photosynthesis and cell respiration

12. How is nitrogen cycled from biotic to abiotic factors?
Decomposition (organisms to the soil)

13. Is more energy available at the top of the food pyramid or the bottom
Is more energy available at the top of the food pyramid or the bottom? Explain.
At the bottom; energy is lost between each trophic level

14. How much energy is lost between each trophic level in a food chain?
90%

15. Sketch an example of a food chain with three trophic levels and use ecology vocabulary terms to label the different trophic levels
Producer -> Primary Consumer -> Secondary Consumer

16. What would happen to the size of the primary consumer population if the number of secondary consumers increased? Explain.
It would decrease as more are being eaten

17. Which of the following receives the least amount of energy
Which of the following receives the least amount of energy? producers, secondary consumers, primary consumers, tertiary consumers
Tertiary consumers

18. What is the definition of a producer?
Makes its own food (glucose) from sunlight energy (photosynthesis)

19. What are some examples of producers?
Plants, seaweeds and some bacteria

20. Match the following terms:
A. Tertiary Consumer
1. Herbivore
B. Primary Consumer
2. Carnivore
C. Producer
3. Heterotroph
D. Secondary Consumer
4. Autotroph
B/1; A, D/2; A, B, D/3; C/4

21. What ecology vocabulary term is defined as an organism that eats both consumers and producers?
An omnivore

22. Match the following with their level in a food pyramid: producer, tertiary consumer, primary consumer, and secondary consumer
Level 1: p; Level 2: pc; Level 3: sc; Level 4: tc

23. What is the advantage of organisms in an ecosystem not having overlapping niches?
Less competition

24. What type of relationship is illustrated in the following graph?
Predator and Prey

25. What is the population size that can be maintained in an area over time?
Carrying capacity

26. Give three examples of factors that would control the size of a population. What are these factors called?
Limiting factors
