This Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.

This activity explores an image of a wildebeest herd on the Serengeti, which serves as a phenomenon for learning about population dynamics and wildlife management.

This activity guides the analysis of a published scientific figure from a study that investigated how herbivore populations are regulated in the Serengeti.

In this activity, students model trophic cascades using cards of organisms from seven different habitats. The activity is designed to illustrate the species relationships in a food chain and the effect of predators on the trophic levels below.

In this video, ecologist Brian Silliman explains how he uses manipulative field experiments to study salt marsh ecosystems. His approach revealed that these systems are under top-down control from consumers and predators.

This video follows ecologist Mary Power, who is studying the Eel River in Northern California to decipher the connection between river flows and biodiversity.

This activity guides the analysis of a published scientific figure from a study that investigated whether periwinkle snails contribute to salt marsh die-offs.

This activity guides the analysis of a published scientific figure from a study on low-oxygen areas in the ocean called dead zones.

This activity explores the content and research discussed in the film Some Animals are More Equal than Others, which tells the story of the ecologists who first documented the role of keystone species in ecosystem regulation.

This film tells the story of the ecologists who first documented the role of keystone species in ecosystem regulation.

In this activity, students use the website WildCam Gorongosa to gather and analyze data from trail camera photos in Gorongosa National Park. Students use this data to predict, plan, and build a biomass pyramid for species in the park.

This video showcases the work of mathematician-turned-biologist Corina Tarnita, who uses quantitative approaches to understand the role of termite mounds in the savanna ecosystem.
