Work samples, phenomena, assessment templates, and videos that directly address standard MS-LS2-3: matter cycling and energy flow in ecosystems.

Kids learn about the food chain and food web. How energy cycles and transfers through living organisms.

[Free Registration/Login may be required to access all resource tools.] Describes how food chains represent feeding relationships.

Learners will use a card sorting activity to construct a food chain and identify the role of organisms within that chain. The cards represent different individuals in an ecosystem and will help students begin to understand the concepts...

Describe the habitat, food web and ecosystem of shark species. Identify threats to sharks and explore how top predators help to maintain the balance of nature within ecosystems. This lesson plan also contains an interactive game.

[Free Registration/Login may be required to access all resource tools.] Based upon the way organisms acquire their energy students will understand how to group them as consumers, decomposers or producers.

Students will understand and describe food chains and food webs, and explain how energy is transferred between their trophic levels.

[Free Registration/Login may be required to access all resource tools.] Describes how to identify trophic levels in a food chain or food web.

Learners learn about energy and nutrient flow in various biosphere climates and environments. They learn about herbivores, carnivores, omnivores, food chains and food webs, seeing the interdependence between producers, consumers and...

This lesson will review the difference between autotrophs and heterotrophs, and show how both play important roles in a food web. It is 2 of 4 in the series titled "Autotrophs vs. Heterotrophs."

Learn about the mysterious jellyfish blooms that have occurred in the world's oceans. Because the resulting alteration to the marine food web has had devastating effects, researchers grow and study jellyfish at the Monterey aquarium....

Describes how a food chain works in a desert and how the Mojave desert food chain works in particular.

This lesson explains the role plants play in the conversion of inorganic materials into organic material to support living things. It is 2 of 3 in the series titled "The Role of Plants in the Food Chain."

This lesson explains the role plants play in the conversion of inorganic materials into organic material to support living things. It is 3 of 3 in the series titled "The Role of Plants in the Food Chain."

Describes the characteristics of a tundra biome, how a tundra food chain compares to a tropical food chain, and what the different trophic levels look like.

Explains what a primary consumer's role in a food chain is and provides examples.

Students explore the biosphere's environments and ecosystems, learning along the way about the plants, animals, resources and natural cycles of our planet. Over the course of lessons 2-6, students use their growing understanding of...

This lesson focuses on food chains in ecosystems, including levels of consumers, decomposers, and a list of common words used with food chains and their definitions. It also provides a link to an assessment.

This lesson focuses on the organization of an ecosystem. The feeding relationships between organisms in an ecosystem can be seen in food chains. Sampling allows us to measure the abundance and distribution of these species. It provides...
