4. What term best describes where all life is found?
5. Name four elements that are found in most organisms.
6. Give an example of an abiotic reservoir.
8. What is the difference between a habitat and a niche?
9. When similar species live in the same habitat, explain how competition between these species is reduced.
10. Name the five main terrestrial biomes found in Canada.
11. The open ocean and a lake are both aquatic biomes. What abiotic factor makes the two biomes different?

12. Predict what would happen if a plant from a deciduous forest were transplanted to the tundra. Explain your
answer.
13. Compare a forest to a bicycle. How are they similar, and how are they different?
14. The black-throated blue warbler migrates from the Caribbean to wetlands in northern Ontario each spring, and
then it flies back again in the fall. Why would the bird make such a lengthy journey two times a year?
15. A crow’s niche is being a scavenger. Is this an accurate description of its niche? Justify your answer.
17. Photosynthesis is the most important process on Earth. Justify this statement. a
18. The paths that nutrients and energy take in ecosystems are different.
(a) Draw a symbol to indicate the path energy takes.
(b) Draw a symbol to indicate the path nutrients take.
19. Suppose that a herd of reindeer had been introduced to a small island that had no reindeer on it and their
population had been monitored. The table below shows the population data.
(b) Suggest why the population of reindeer was lower in 1940 than in 1935. Several different plausible
extrapolations are possible. Suggest one or more, and be prepared to explain your predictions.
20. When a predator catches its prey, it may appear that the prey species suffers. But
there are benefits to this type of interaction for the prey species as well. What are two ways in which the prey
species may benefit from the predator hunting them?
21. Bacteria can reproduce so quickly that, under ideal conditions, one bacterium could produce enough bacteria to
cover the entire planet in only a few weeks. Explain why this does not happen.
