Aquatic Food Webs

Here is a practical activity for reinforcing understanding of energy flow in ecosystems. Learners identify whether each organism in a list is a producer or decomposer. They tell if each is an herbivore, carnivore, omnivore, or...

Can a piece of art represent an ecosystem? Young scientists view Oval Basin (attributed to Bernard Palissy) and identify the ecosystem pictured, then sort the living things into producers, consumers, and decomposers to create a food web.

Students explore the relationships within the food chain between plants and animals. They construct modules of food chains, keeping them simple and not complex. They focus on what the animals eat and not on what eats it.

In spring, the Bering Sea turns green due to phytoplankton, which live at the surface, experiencing a population explosion. Groups of scholars play a food chain game, writing down food chains as the game is played. After five to six...

In this food web design learning exercise, students sketch and create an illustration of a food web of a chosen habitat area. Students label the types of feeders and use correctly oriented arrows to show the feeding relationships to show...

Skulls tell it all, and with this lesson plan, you will tell it all to your class! Youngsters view animal skulls, analyzing the shape of teeth and the placement of the eye sockets. They associate these adaptations with the types of food...

When a minnow eats a piece of plastic, that garbage often tracks through multiple animals, causing harm to each as it passes through the food chain. Scholars learn about food chains, food webs, and energy pyramids with a presentation. It...

Explore the food chains that support Arctic ecosystems. A class discussion on interdependence and the different roles plants and animals play in ecosystems provides students with the knowledge to complete a worksheet asking them to...

Fifth graders interpret a table of data about food chains in the ocean. They create a food chain to represent the information on the table. Periwinkles eat seaweed, and crabs eat periwinkles - so who eats crabs? Extend the activity with...

Rhinozilla is Mia's bearded dragon and the focus of this lesson on energy flow in an ecosystem. She uses him to explain the energy pyramid, from producers through third level consumers, and she likens the food chain to a video game. Mia...
