Use this model to answer the questions below:
What does the chameleon eat in this food chain?
How does the Chameleon grow and thrive?
Criteria For Success:
Identify what the animal eats.
Explain how the animal use food molecules to grow.
Explain how the animal use other food molecules.
The chameleons eat _____________. Chameleons grow by ____________ and use other food molecules for ____________
We can’t bring an ecosystem into the classroom. Even if we could, it would be impossible to see the molecules in organisms and trace them back to where they came from.
Food Web Model Directions
Move through the ecosystem and look for something you eat or something that eats you.
When you find something you eat or that eats you, hold on to the yarn. If there is no yarn in your food web yet, stay close to the others in your food web.
Once you have four organisms in your food web, sit in a circle and say, "Food web!"
The model is complete when all organisms are part of a food web.
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?
Criteria For Success:
Explain what happened to the molecules when one organism ate another organism.
Explain where did all the food molecules go.
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?
If there were no carps or frogs, then __________________
What do you think would happen to your food web if there were no plants or algae?
If there were no plants or algae, then __________________
Check For Understanding:
Where do food molecules in an ecosystem come from?
Food molecules in an ecosystem come from __________________
DIRECTIONS: Use the Florida Everglades Food Web to answer the following questions.
Use the food web to answer the question.
What would happen if there were no grass carp?
What would happen to the rabbits and grass carp if there were no marsh grasses? Why?
