To demonstrate, slightly crack a hard-boiled egg and show how the pieces shift around. Review the flow of energy in food pyramids. Then have students research a vent creature in MSB Explores the Ocean and reference books. Three-foot worms rise from the sea floor. Giant clams and anemones are filter feeders - grabbing food out of flowing water.
Crabs are scavengers.
As a class, create a vent food pyramid and compare it to a non-vent one. All rights reserved. Terms of use.
