1. Define ecology. (p.819)
2. Define biotic factors and describe
their effects on ecological interactions.( p. 819-820)
3. Define abiotic factors and
describe how each of the following abiotic factors affects ecological
interactions: availability of water, changes in temperature, amount of
light present in the environment, availability of organic and inorganic
nutrients, and composition of the soil . (Section 37-1)
4. Describe the make-up of the earth's biosphere.
(p. 824)
5. Describe the make-up of the
earth's atmosphere and understand the biological importance of the earth's
atmosphere to life including: (p.831-834)
i) its composition
relative to the presence of gases vital to life as we know it,
ii) its role in protection
against radiation, and
iii) its role as heat sink
(climate control).
6. Explain how life is dependent upon the
recycling of matter by using the nitrogen cycle, the carbon cycle, and
the oxygen cycle as examples. (p. 831-833)
7. Explain how the normal carbon dioxide balance
on earth has been altered and how this shift affects the global environment
(greenhouse effect). (p. 833)
8. Relate how life in the biosphere is dependent
upon the constant changing of water from its liquid to its gaseous phase
in a sequence of changes called the hydrologic (water) cycle. (p. 834)
9. Explain the importance of solar energy
to life on earth and summarize how such energy is captured and transformed
in an ecosystem. (p.830)
10. Explain the flow of energy in an ecosystem
using the concept of a pyramid of energy. (p.830)
11. Explain how energy availability affects
the total mass of organisms in an ecosystem and summarize this relationship
in a pyramid of biomass. (p. 830)
12. Explain how energy availability affects
the number of organisms present at each trophic level and summarize this
relationship in a pyramid of numbers. (p. N/A)
13. Illustrate, by example, the degree of
efficiency of the flow of energy in an ecosystem in an ecosystem in terms
of the capture and transfer of the sun's energy. (p. 830)
1. Define biome. (p. 845-846)
2. Explain how a biome develops
and identify how abiotic factors (altitude, temperature, precipitation,
and light) determine a particular biome. (p. Sections 38-1, 38-2)
3. Describe the main terrestrial biomes of
Canada: tundra, taiga, temperate deciduous forest, and grasslands.(p.846-849)
4. Identify the characteristics of tropical
rain forests and deserts; note the global impact of both the destruction
of tropical rain forests and the spread of deserts. (p. 849-852)
5. Describe marine and freshwater
biomes. (p. Section 38-2)
6. Describe how differences in abiotic factors
affect life in aquatic biomes contrasted with terrestrial biomes.(p. Sections
38-1, 38-2)
1. Define habitat. (p. 826)
2. Define niche and relate it to habitat.
(p. 826)
3. Define competition and explain how competition
arises among organisms. (p. 826-828)
4. Differentiate between interspecific and
intraspecific competition. (p. 826-828)
5. Describe the feeding relationships in an
ecosystem in terms of competition, food chains, and food webs.(p. 826-829)
6. Show how the many interrelated food chains
(food web) of an ecosystem give a community stability and identify the
conditions necessary for a stable, self-sustaining ecosystem. (p. 828-829,
835)
7. Illustrate with examples how special symbiotic
relationships allow plants and animals to take advantage of one another
to find food, shelter, protection, and to aid in reproduction (e.g. commensalism,
mutualism, parasitism). (p. 824-826)
8. Illustrate, with examples, how symbiotic
relationships help in maintaining stability in the ecosystem. (p.824-826)
9. Explain, by using knowledge about diversity
of organisms, complexity of food webs, special symbiotic relationships,
energy flow, and environmental limitations, why ecosystems can change.
(p. summative)
1. Define ecological succession. (p. 835)
2. Describe the main factors responsible for
ecological succession: climatic and geographical forces plus change in
a community caused by its own inhabitants. (p. 835, 845)
3. Define: dominant species, climax community,
primary succession, and secondary succession. (p. 835-836)
4. Explain how primary succession differs
from secondary succession. ( p. 836-838)
5. Explain how succession on land which leads
to the development of a forest community differs from succession in lakes
and ponds. (p. 836-839)
6. Describe the fragility and stability in
ecological communities by making reference to the restricted dependence
of life in a biome. ( p. 835, 845, 854)
