Explain the difference between a producer and consumer.
Explain the difference between a primary consumer, secondary and tertiary consumer.
Compare and contrast herbivores, omnivores, and carnivores.
Explain a food chain.
Combine different food chains together to create a food web and explain how different organisms are related.
Explain an energy pyramid (what happens to the energy as you move up the pyramid, which type of organism is
found at each level).
Explain what happens to population size and biomass as you move up the pyramid.
What is the 10% rule and what type of pyramid does it relate to?
Describe the levels of organization for ecosystem.
Describe the 6 major biomes of the world
a. Abiotic factors
b. Dominant biotic
c. General location
Ecology is _______________.
Darwin and evolution
Genetics and genetic mutations (know all key terms for genetics)
Be able to solve problems involving complete dominance, incomplete dominance, codominance, multiple alleles and sex
linked traits.
