Includes a food web that is labeled with producer, consumer, herbivore, carnivore, apex predators and the trophic levels. Also includes an animation of how over fishing can lead to a decline in a sea otter population and result in a new ecosystem being formed due to the loss of kelp. This animation was created in line with a worksheet created by MCPS, and therefore could not be uploaded to accompany the animation.
Can be used to help create an assignment.
I gave my students a description of what each animal ate and had them create a poster.
"With your group make a Food Web based on the feeding relationships given.
a. Draw a line from each organism to the animal that eats it.
b. Do one food chain at a time.
c. Be sure not to confuse the eating animals with the animals they eat!
When you are finished LABEL THE FOLLOWING on your poster.
a. Label each organism as a PRODUCER or a CONSUMER.
b. Label the consumers as either an HERBIVORE, CARNIVORE or OMNIVORE.
c. Label any APEX PREDATORS.
d. Choose ONE food chain and label the TROPHIC LEVELS (Producer, Primary Consumer, Secondary Consumer, Tertiary Consumer)
Then, I gave them a reading about what happened when killer whales switched their diet from sea lions and seals to sea otters and had them answer questions.
