Ecology Review Sheet
_Review
all the materials in your science binder AND this website. There are some interactive links on this
website that will also help you review the materials.
1. You should be able to define and explain each of the following terms AND give an example of each.
a. Habitat
b. Carnivore
c. Herbivore
d. Omnivore
e. Decomposer
f. Food chain
g. Food web
h. Strand (draw your example in a food chain)
i. Trophic level (no example needed here)
j. Producer
k. Primary consumer
l. Secondary consumer
m. Tertiary consumer
n. Hierarchy of complexity
o. Individual
p. Population
q. Community
r. Ecosystem
s. Biome
t. Biosphere
2. The word, biosphere, is made up of two root words, ‘bio’ and ‘sphere’. What do these root words mean?
3. Where does the biosphere extend to?
4. Draw interconnecting food chains (e.g., a food web) from the following information provided about the organisms:
polar bears eat seals, killer whales eat seals & salmon, wolves eat caribou and salmon, caribou eat tundra plants, eagles eat large and small fish including salmon, snowy owls eat lemmings, lemmings eat tundra plants, seals eat large fish (including salmon), large fish eat small fish and crustaceans, small fish and crustaceans eat plankton (photosynthesizing organisms). Crabs eat dead organisms.
5. You should be able to fill in the different levels of the trophic pyramid and give an example for each level. For practice, use the food web you created in question #2.
6. How is a population more complex than an individual?
7. How is an ecosystem more complex than a community?
8. How do abiotic factors influence where an organism lives?
9. What are the two main things that define a biome?
10. Define climate.
11. List the 3 main climate zones. Describe what characterizes them.
12. List and describe at least 3 terrestrial biomes.
13.In our model habitat and/or the sphinx moth caterpillar observations, what were some ways that the organisms changed their habitat?....and how did the habitat change the organism?
