Trophic Levels

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

Which of the following is a TRUE statement about trophic levels?

An organism that uses an outside source of energy like the sun to create food is a...

• Producer

• Consumer

• Parasite

• Decomposer

The first trophic level includes

• Carnivores

• Primary Consumers

• Producers

• 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.
