​Time to fill out your Ecosystem Information Sheet!

Use the information on the websites below to fill in the "General Description", "Important Biotic Factors", and "Important Abiotic Factors" sections of your sheet.

https://floridadep.gov/rcp/saltmarshes

21

​Keep it up! Here's more information for your EIS.

Use the information on the websites below to fill in the organisms on the "Food Pyramid" section of your sheet.

https://www.dnr.sc.gov/marine/pub/seascience/dynamic.html

https://soils.ifas.ufl.edu/florida-wetlands-extension-program/about-wetlands/types-of-wetlands/tidal-salt-marshes/

(HINT: Scroll to the section titled "Salt Marsh Wildlife" and read from there.)

22

​What about adaptations?

You can probably already fill in the information about at least one adaptation, but the website below may help you complete this part of your sheet.

23

​Symbiosis in the Salt Marsh

You may have been having trouble finding examples of symbiosis in the salt marsh ecosystem. The two sites below will give you some really interesting examples of both mutualism and parasitism.

https://researchblog.duke.edu/2017/06/24/marine-parasites-little-guys-that-make-a-big-difference/

Remember that in your descriptions of symbiotic relationships, you should name the type of symbiosis, name each organism involved, and specify how each organism is affected in the relationship.

24

Open Ended

Based on the second article, how can a parasite actually be beneficial to an ecosystem as a whole?

25

​Time to Finish that Ecosystem Information Sheet

You should now be able to fill in the "Real-World Examples" and the "Unique or Interesting Facts" if you haven't already. If not, check out the links below.

Multiple Choice

What percentage of energy is transferred from one trophic level to the next?

1

10%

2

50%

3

100%

4

1%

27

Multiple Select

Which of the following are functions of salt marshes?

1

Buffering wave action

2

Trapping sediments

3

Increasing flooding

4

Filtering runoff

28

Multiple Select

Why is understanding energy movement, such as the '10% Rule,' important for studying ecosystems like salt marshes?

1

It helps explain how nutrients cycle in the ecosystem.

2

It shows how much energy is lost at each trophic level.

3

It reveals why some organisms are more abundant than others.

4

It helps us understand the impact of species loss on ecosystems.
