ER 3.3: Differences In Soil

Objective: KWBAT gather and analyze evidence from the simulation for how decomposers affect the soil.
Question 1

Soil can be made of:

Question 2
2.

Organisms that break down dead matter are

Question 3
3.

Which of the following are decomposers?

1
Question 4
4.

Which of the following organisms is a producer?

1
Phytoplankton are microscopic organisms that float in the ocean. They take in sunlight to make their own food.

1
Question 6

Are phytoplankton considered to be producers or consumers?

Question 7
7.

Explain why phytoplankton are considered to be producers or consumers.

Simulating Different Soils

You will use the Simulation to investigate what happens to the soil and the organisms in an ecosystem when the nutrients are removed.

Our Investigation Question:
Why is the matter that makes up soil different in different places?

Directions: Investigating Soil in the Simulation
  • Login to the Sim by clicking the link below
  • https://learning.amplify.com/ecosystemrestoration/#/
  • Use the Simulation to investigate why the matter that makes up soil can be different when something changes in the ecosystem.
  • Try making different changes to the soil. Observe what happens to the soil and to the other organisms in the ecosystem.
  • Use the results of your investigation to answer the questions below.
Question 8
8.

There are two ways that you can change the soil. What happens if you remove the water from the soil (click the soil to remove the water)?

Sentence starter: If you remove the water from the soil, then _____________________

Question 9
9.

What happens if you remove the decomposers from the ecosystem (click the mushrooms to remove the decomposers)?

Sentence starter: If you remove the decomposers from the ecosystem, then _____________________

Question 10
10.

Based on what you observed in the Simulation, what do you think could make the soil different in one part of the rain forest than in another part?

Sentence starter: Soil can be different in parts of the rain forest because _____________________

Question 11
11.

Based on what we learned, do you have any new ideas about why the cecropia trees are not growing and thriving in the restoration project site?

Sentence starter: The cecropia trees are not growing and thriving in the restoration project site because _____________________

Synthesizing Ideas About Differences in Soil

You will synthesize the information you have gathered to come to new understandings about how soil can be different in different places.

New Understanding About Soil:

Write a one sentence summary of what we’ve learned from these sources to answer our question:

Why is the matter that makes up soil different in different places?

Use the words: soil, nutrients, and decomposers

Question 16

Based on the evidence you have gathered, why do you think there are more nutrients in soil with decomposers?

Investigating How Decomposers Get Food Molecules

In the Simulation gif below, observe the energy flow between organisms in the Simulation and focus on the decomposers.
