If you wanted to visualize information about how the energy changes in an ecosystem, it would be best to use the following model:
Food chain
Trophic pyramid
Food web
How much energy passes from a lower trophic level to the level above it?
1%
10%
100%
1000%
Which of the following is a TRUE statement about trophic levels?

Decomposer
The first trophic level includes
Carnivores
Primary Consumers

Herbivores
Organisms that have to eat other organisms are called
Autotrophs (producers)
Heterotrophs (consumers)
Please identify all of the conventions that the model above uses
Multiple diagrams or images
Made something invisible...visible (ex. zoom ins, molecules, temp)
Arrows
Showed the sequence of events
Key and/or labels
If you were to give feedback to the person who made this model, what would you say and why? What could they add to make the model better? Remember the model conventions are: multiple images, made something invisible...visible, arrows, sequence of events, keys or labels, and textboxes/captions.
