Second Semester Benchmarks:
6a. Students know biodiversity is the sum total of different kinds of organisms and is
affected by alterations of habitats.
6b. Students know how to analyze changes in an ecosystem resulting from changes in
climate, human activity, introduction of nonnative species, or changes in population size.
6. c. Students know how fluctuations in population size in an ecosystem are determined by
the relative rates of birth, immigration, emigration, and death.
6d. Students know how water, carbon, and nitrogen cycle between abiotic resources and
organic matter in the ecosystem and how oxygen cycles through photosynthesis and
respiration.
6e. Students know a vital part of an ecosystem is the stability of its producers and
decomposers.
6f. Students know at each link in a food web some energy is stored in newly made structures
but much energy is dissipated into the environment as heat. This dissipation may be
represented in an energy pyramid.
6g.* Students know how to distinguish between the accommodation of an individual
organism to its environment and the gradual adaptation of a lineage of organisms through
genetic change.
8b. Students know a great diversity of species increases the chance that at least some
organisms survive major changes in the environment.

Define a population and four factors affecting populations.
After a volcano, plants quickly recolonize the burned area. Are those
plants more likely to be r-strategists or K-strategists? Explain your
answer.
How do density-dependent and density-independent controls affect
growth of a population?
What is a food chain and what always begins the chain?
Define & give an example of each of these consumers --- herbivore,
carnivore, omnivore, detritivores, & decomposer in a food web.
In terms of energy passage, why will there be many more producers
than herbivores and fewer large carnivores than small carnivores?
Where does the energy go that is lost in a energy pyramid?
Biomes are controlled by what two climatic factors?
List the major biomes and characteristic climate of each.
Define biodiversity. Which biome has the most biodiversity?
What are biogeochemical cycles, why are they important?
What 2 processes form the basis for the carbon cycle
How do condensation, precipitation, transpiration and evaporation
contribute to the water cycle?
Describe how bacteria participate in the nitrogen cycle.
Describe the flow of phosphorus through an ecosystem.
Describe succession the 2 types of succession. What do they start
and end with?
List how humans are causing changes in ecosystems and the possible
effects they are causing.
What is biomagnification and give an example from real life
explaining its effects.
What are the major causes for extinctions of plants and animals?
Why is the introduction of species from other areas not a good idea?
