Unit 6: Ecology IntroDoc

Last updated almost 4 years ago
20 questions
Standards 2.A.1; 2.B.2; 2.B.3; 2.C.1
Essential Questions: You will be able to answer:
* How do biotic and abiotic factors affect the carrying capacity and biodiversity of an ecosystem?
* How does matter cycle and energy flow in an ecosystem?
* How does photosynthesis, cellular respiration, decomposition, and combustion cycle carbon?
* Why do populations maintain their size when conditions remain stable but can change when the ecosystem changes?

The Learning Goals:
  • I can explain the nature of interactions between organisms in predator/prey relationships and different symbiotic relationships.S
  • I can explain how cooperative and competitive predator/prey relationships help maintain balance within an ecosystem.
  • I can describe the flow of energy and matter within a food web.
  • I can explain why there are generally more producers than consumers in an energy pyramid.
  • I can predict how the use and flow of energy will be altered due to changes in a food web.
  • I can explain the processes of recycling nitrogen, oxygen and carbon in an ecosystem.
  • I can explain the importance of the recycling of nitrogen, oxygen, and carbon within an ecosystem.
