Create a diagram in which you illustrate the energy flow among organisms of a food chain in a particular ecosystem.
Select an ecosystem, such as a temperate forest, desert biome, or the Everglades.
Determine the interdependency of life in your ecosystem by examining its organisms.
Include the following:
· List the organisms that can be found in your ecosystem. What is the benefit of this biodiversity?
· Label major organisms that live in your selected ecosystem: P for producers, C for consumers, and D for decomposers.
Write a summary of your food chain that:
· Describes the major categories of organisms: producers, consumers, and decomposers.
· Describes the interactions between organisms in your ecosystem.
· Evaluates potential hazards caused by humans that might affect your ecosystem’s stability, such as environmental pollution. What effect does this hazard have on the biodiversity in your ecosystem?
· Lists the abiotic factors present in your ecosystem.
· Describes the food chains associated with your ecosystem. Address the following items:
o Name of the plant or animal
o What it eats
o What eats it
o How it has adapted to the ecosystem
|Content and Development
|All key elements of the assignment are covered in a substantive way. The diagram includes the following:
Shows the flow of energy of the food chain
Lists organisms present in the ecosystem and identifies their contribution to biodiversity
Labels major organisms as producers, consumers or decomposers
The paper includes the following:
Describes the interactions of organisms in the ecosystem
Evaluates potential hazards caused by humans
Lists abiotic factors present in the ecosystem
Lists and described the food chains present in the ecosystem
Name of the plant or animal
What it eats
What eats it
How it has adapted to the ecosystem
|Nice work showing the flow of energy, listing organisms, identifying the importance of biodiversity, and labeling organisms as producers, consumers, or decomposers.
Great job listing and defining your food chain, describing interactions and evaluating the potential hazards caused by humans.

|Overall Comments: Great way to finish off this course. It has been a pleasure working with you during the past nine weeks. I hope this assignment provided more insight into food web diagrams. You created a web and analyzed it using the principles of ecology. Nice work describing interactions and labeling producers and consumers, identifying abiotic factors and evaluating threats to biodiversity. I wish you the best of luck in your future endeavors!
