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.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? 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 -gt Primary Consumer -gt 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?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

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

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

following graph?
Predator and Prey
25
What is the population size that can be
maintained in an area over time?

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

• Limiting factors
