Ecosystem Model
Use the picture below to answer the questions

1

What 2 things happen to the grass molecules once they are eaten by the zebra?

Sentence starter: The grass molecules ___________________

1

What 2 things happen to the zebra molecules once they are eaten by the cheetah?

Sentence starter: The zebra molecules ___________________

Where do food molecules in an ecosystem come from?

Food Chain

What do the arrows represent in this model? Use the words direction and food matter (molecules) in your answer. Read page 14 to help you answer this question.

Sentence starter: The arrows represent ____________________

Food Web

0

What does a food web show? Read page 16 to help you answer this question.

Sentence starter: A food web shows ____________________

Use the food web to answer questions 8

3

Start with the algae and follow the arrows up to the alligator. Use the food web to fill in the food chain below.

Draggable item		Corresponding Item
mosquito		8.1
frog		8.2
raccoon		8.3

Use the food web to answer questions 9

3

Start with the algae again, but this time, find a different way up to the alligator. What eats what in this ecosystem?

Draggable item		Corresponding Item

Where does the alligator get its food molecules?

Sentence starter: The alligator gets food molecules from _____________________

1

What are two organisms (living things) in the picture to the right? What is something that is NOT an organism (nonliving)?

Sentence starter: Two organisms are the _________ and the _. ___________ is not an organism.

0

The cards describe the relationships between different organisms in the food web.
-Use the relationships AND the scribble tool to draw arrows showing how matter moves through the ecosystem.
-Your arrow should point in the direction that matter moves.
-Let's do the raccoon together as an example.

Each set of cubes represents the body matter of the organism. 

Watch the video, then answer the questions below.

0

The cubes for represent food/body matter (molecules) for each organism (living thing)

What was happening to the molecules in the ecosystem as the cubes (the matter) were getting passed from one organism to the next?

The Food Web Model can help us think about how matter flows when something in the ecosystem changes.

What do you think would happen to your food web if there were no carp or frogs?

0

What do you think would happen to your food web if there were no plants or algae?
