Life Science Unit I Test
Review
1. Describe how living things interact on several levels of organization: organism, population, community, ecosystem, and biosphere.
2. Describe the role of organisms as producers, consumers, herbivores, carnivores, or decomposers in an ecosystem. Give examples of each.
3. Describe how predators and prey control each other’s population.4. Define symbiosis and describe three types of symbiotic
relationships: mutualism, commensalism, and parasitism. Give examples.
5. Describe how biotic and abiotic factors can influence an ecosystem.
6. Describe a simple food chain or food web using the words producer, consumer (primary, secondary and tertiary) and trophic level.
For this unit, you should be able to:
7. Describe how energy flows through ecosystems with reference to the pyramid of energy, pyramid of numbers and pyramid of biomass.
8. Describe several abiotic factors that influence the distribution of living things.
9. List and describe characteristics of each of the eight different biomes you studied. Provide characteristic plants and animals.
10. Describe how organisms become adapted to the environment using vocabulary such as mutation, adaptation and natural selection.
11. Provide examples of different adaptations that predator and prey species may have to help them survive.
For this unit, you should be able to:
12. Describe the role of biodiversity in stabilizing an ecosystem.
13. Define keystone species and give an example.14. Define how competition can occur between species
and within species in a community and what may result.
15. Describe how resource partitioning can lead to adaptive radiation.
16. Provide examples of foreign species and possible impacts of their introduction into an ecosystem.
17. Distinguish between primary and secondary succession , and describe the role of pioneer species in succession
For this unit, you should be able to:
