Project #9926 - Unit 1

In this assignment, you will investigate the biotic and abiotic structure and function of an ecosystem.

Choose one of the following ecosystems:

  • Tropical rainforest
  • Grassland
  • Coral Reef
  • Estuary
  • Desert

You will write a two to three page APA-style research paper about your choice of ecosystem including:

  • Where might this type of ecosystem be located? Give one specific example.
  • Describe the structure of the ecosystem: List both the abiotic components and biotic components
  • Describe the function of the ecosystem: How do the abiotic and biotic components interact in biogeochemical cycles? Describe both the carbon and nitrogen cycles
  • Describe disturbance and recovery: Describe one natural and one human caused disturbance to the ecosystem. Explain the damage to the ecosystem, including how the abiotic and biotic characteristics of the ecosystem changed.
  • Explain how ecosystems recover naturally based on resilience mechanisms and the theory of secondary succession.

The following grading rubric will be used for this assignment.
