Abiotic Reservoirs for Phosphorus Assignment

Abiotic Reservoirs for Phosphorus Assignment

The purpose of the Module 2 Lab is to explore ecosystem components and dynamics.

You will have the opportunity to develop skills/knowledge in:

• defining basic ecology terms and concepts, such as biome, productivity, biodiversity, etc.
• distinguishing biotic from abiotic ecosystem components and processes
• defining soil properties and differentiating good versus poor soil health
• analyzing the relationship between soil health, climate change and grazers
• evaluating the use of grass-based livestock to enhance soil health and store atmospheric carbon

In order to complete this module, you will complete the following tasks:

• Answer the questions on the following word document assignment ACTIONS and submit on this assignment page.
• Reference the What to do Module 2 page and the following phosphorus cycle figure in the lab.

Use the following criteria/tips for success:

• Reference the grading rubric for this assignment
• Don’t forget that you have a lab group discussion page!
